Captchas and Accessibility: Balancing Security with Inclusivity

CAPTCHAs are a ubiquitous part of the internet, used to verify that a user is human and not an automated bot. You might have encountered them by clicking on boxes to select images of traffic lights, deciphering distorted text, or simply checking a box that says, "I am not a robot". For many, this is a minor inconvenience, but for individuals with disabilities, it can be a major barrier to accessing online services.

CAPTCHAs, short for Completely Automated Public Turing tests to tell Computers and Humans Apart, are a crucial part of digital security. They prevent bots from abusing online services by filling out forms, creating fake accounts, spamming messages. As bots have gotten more sophisticated, CAPTCHA technologies have also evolved, becoming more difficult and diverse in nature. But here’s the problem: while CAPTCHAs have become more difficult for bots, they’ve also become more difficult for humans, especially those with disabilities.

In today's digital landscape, CAPTCHAs present major hurdles for individuals with disabilities, limiting their access to crucial online services. According to the European Union, approximately 101 million people, or one in four individuals, live with some form of disability. By implementing accessible CAPTCHAs, businesses can expand their customer reach, comply with legal standards, and improve overall brand perception. By implementing accessible CAPTCHA solutions, businesses foster a more inviting user experience, reduce bounce rates, and enhance their brand’s appeal to a broader audience. Accessible CAPTCHA solutions are not just a compliance necessity but also a practical business approach that creates a more welcoming environment for all users.

Accessibility and CAPTCHAs

Ensuring CAPTCHA accessibility means designing these systems to be usable by everyone, regardless of individual abilities. Traditional CAPTCHA challenges, such as distorted text or complex image selection, often create barriers for people with visual, auditory, or cognitive impairments. When CAPTCHAs require image identification, users with visual impairments often find these tasks insurmountable. Audio CAPTCHAs provide little assistance for those with auditory impairments, while individuals with cognitive impairments often find timed puzzles or complex challenges to be frustrating and exclusionary. Accessibility in CAPTCHAs aims to remove these barriers by designing verification methods that are usable by all individuals, while remaining effective against automated systems.

A key goal of CAPTCHA accessibility is to comply with standards such as the Web Content Accessibility Guidelines (WCAG), which outline how to make web content usable for people with disabilities. In the European context, the EN 301 549 standard is crucial, as it is based on WCAG and serves as the official European standard for accessibility. The European Accessibility Act (EAA), especially Directive (EU) 2016/2102, requires compliance with EN 301 549, and thereby WCAG, ensuring that digital services, including CAPTCHAs, are accessible to all users across the European Union.

For businesses, implementing accessible CAPTCHA solutions is not just about meeting legal obligations under regulations like the European Accessibility Act. It is also about enhancing user experience and improving customer retention. Accessible CAPTCHA solutions mean fewer obstacles for users, which leads to lower bounce rates and a more positive interaction with online services. This inclusive approach enhances brand reputation, helping businesses connect with a wider, more diverse audience.

Different CAPTCHAs, Different Accessibility Challenges

CAPTCHAs come in many forms, each presenting a unique set of accessibility challenges. Let’s take a closer look at different types of CAPTCHAs and the obstacles they can pose for people with disabilities.

Behavioral-Based CAPTCHA Challenges

Behavioral-based CAPTCHA challenges work by identifying natural human behaviors, and they can be broadly divided into two types: user interaction signals and contextual environment signals. User interaction signals focus on the nuances of how a person navigates online. These include subtle variations in mouse movements, typing rhythms, and the timing of different interactions. These characteristics are difficult for bots to replicate. On the other hand, contextual environment signals involve factors like IP reputation, connection quality, and device characteristics, providing a way to gauge user legitimacy without direct user engagement.

While analyzing user interaction can feel intuitive and seamless for many users, it does present difficulties for those relying on adaptive technologies or who have motor impairments, potentially creating unintended accessibility barriers. By contrast, contextual environment signals operate quietly in the background, assessing legitimacy without the need for user actions, thus offering a more accessible approach with minimal impact on the user experience.

Proof-of-Work CAPTCHA Challenges

CAPTCHA Challenges based on Proof-of-work are worth mentioning separately because they represent a simple form of environment analysis that runs on the client side. They do not have direct accessibility concerns since they operate passively. In proof-of-work challenges, the user’s device performs a minor computational task, creating a workload for the computer but requiring no direct user input. As a passive mechanism, they present minimal accessibility issues, making them an effective complement to other forms of verification by providing an additional layer of security without complicating user interaction.

When considered alone, proof-of-work challenges are ineffective at accurately discriminating between bots and real users. They rely on the user's device to complete a computational task, but this does not definitively verify the presence of a human. The idea behind this type of challenge is to make bot attacks economically impractical by adding a computational cost to each attempt, thus slowing down attackers. This computational delay makes large-scale automated attacks less feasible when launching numerous automated requests, while remaining lightweight enough to avoid negatively affecting legitimate users. Because of their limited ability to detect the presence of actual human interactions, they should only be used in conjunction with other CAPTCHA challenges to add an extra layer of security when it comes to bot detection.

Text-Based CAPTCHA Challenges

The earliest form of CAPTCHA, text-based CAPTCHAs, requires users to decipher distorted letters and numbers. While these CAPTCHAs are still in use today, they come with notable accessibility challenges that impact a broad range of users. Since the text is often presented as an image, screen readers are unable to interpret the content, which creates a significant barrier for visually impaired users. This issue necessitates the development of more accessible alternatives, such as audio challenges or behavioral analysis, which can offer a more inclusive experience.

Beyond visual impairments, colorblind individuals can also face difficulties when interacting with text-based CAPTCHAs, especially if the contrast between the text and the background is inadequate. These contrast issues can make it nearly impossible to accurately identify the characters. Even users without specific disabilities often find text-based CAPTCHAs frustrating due to the degree of distortion, which can make the text nearly illegible. This universal difficulty raises questions about their overall effectiveness and usability, suggesting that a shift towards more user-friendly solutions is both necessary and beneficial.

Overall, while text-based CAPTCHAs have played an important historical role in preventing automated abuse, their inherent limitations highlight the need for more advanced, accessible, and effective solutions.

Image-Based CAPTCHA Challenges

Image-based CAPTCHAs usually ask users to click on images that contain a specific object, like the well known call to "click on all the traffic lights". While this might be easy for those with typical vision, it’s challenging for people with low vision or color blindness. Identifying subtle visual differences, such as distinguishing between various shades or recognizing partially obscured objects, can be nearly impossible for many users in these groups, which underscores the need for more inclusive alternatives.

Beyond visual impairments, cultural differences further complicate the effectiveness of image-based CAPTCHAs. Many of these challenges rely on users recognizing culturally specific items, such as fire hydrants, street signs, or particular types of vehicles. For instance, a "fire hydrant" may be entirely unfamiliar to individuals from regions where hydrants look significantly different or are not as commonly visible. This cultural bias can cause the CAPTCHA task to not only be frustrating, but also exclude users of diverse backgrounds, ultimately limiting its effectiveness as a security measure.

The accessibility issues associated with image-based CAPTCHAs highlight their shortcomings in terms of providing a consistent user experience. By excluding individuals based on either visual ability or cultural familiarity, these challenges often fail to meet the needs of a global and diverse internet audience.

Audio CAPTCHA Challenges

Audio CAPTCHAs were initially introduced as an alternative to visual CAPTCHAs, primarily to support users with visual impairments. This solution aimed to create a more inclusive verification method. However, audio CAPTCHAs come with their own unique set of challenges that impact different user groups. For individuals with hearing impairments, particularly those with partial hearing loss, the distorted and often garbled nature of these audio clips can make it extremely difficult to understand the content. This poses a significant barrier, reducing the accessibility they were intended to provide.

Moreover, audio CAPTCHAs are often impractical for users in environments where playing audio aloud is not feasible, such as in public spaces or workplaces. Users in noisy environments may also struggle to discern the distorted audio over background noise, which makes completing these challenges frustrating and inconvenient. The audio quality itself can be an additional hurdle, as the robotic, heavily modified voice can be especially difficult for non-native speakers to comprehend, or for individuals with auditory processing disorders who might struggle with separating speech from background distortions.

Some variations, such as question-based audio CAPTCHAs that use clear, spoken phrases, have emerged to address these accessibility issues. These more straightforward audio challenges are easier for users to understand and significantly improve the verification experience for those who struggle with typical distorted audio. However, the simplicity that makes these CAPTCHAs more inclusive also makes them more vulnerable to automated attacks. This vulnerability highlights the need for balance: while accessibility is essential, maintaining security is equally important.

To effectively address these issues, it is beneficial to pair audio CAPTCHA challenges with additional verification methods. Behavioral analysis, which examines natural human interactions, or contextual environment signals, which assess device and network characteristics, can help enhance security without compromising on inclusivity. By integrating audio CAPTCHAs into a multi-layered verification strategy, we can strive towards a solution that accommodates a wide range of users while also maintaining the robust defense needed to protect online systems.

Logic-Based CAPTCHA Challenges

Logic-based CAPTCHAs take a different approach by engaging users through simple puzzles or tasks that are easy for humans but challenging for bots. Examples include solving basic math problems like "What is 2 + 2?", arranging rotating shapes into a specific orientation, or answering straightforward questions. These challenges aim to be more interactive and less frustrating compared to deciphering distorted text or identifying obscure objects in images.

One of the main benefits of logic-based CAPTCHAs is their potential to create a more enjoyable user experience. Unlike text or image-based challenges, these tasks are often more engaging, making the verification process feel less like a chore. However, despite these advantages, logic-based CAPTCHAs still have notable accessibility limitations. Users with cognitive impairments or learning disabilities may find even simple puzzles overwhelming. Tasks involving visual-spatial reasoning can be particularly difficult for individuals with disabilities or those who use assistive technologies. Visual elements like rotating shapes can also create barriers for users with visual impairments, reducing the inclusiveness of these challenges.

When thoughtfully designed, logic-based CAPTCHAs can enhance accessibility and inclusivity. Tasks should be simple, clearly explained, and provide ample time for completion. These adjustments can make logic-based CAPTCHAs less intrusive and more accessible while still maintaining the necessary level of security. By integrating logic-based CAPTCHAs with other verification methods, they can offer a balanced solution that enhances user experience without compromising on security or accessibility.

CAPTCHA Accessibility: Legal Requirements and Guidelines

When evaluating accessible CAPTCHA solutions, numerous conventional approaches fall short of meeting key accessibility standards, as previously discussed. Many of these systems, especially those relying on distorted text or complex images, fail to accommodate individuals with visual impairments, particularly those using screen readers. Audio CAPTCHAs, though designed as an alternative, often pose substantial difficulties for users with hearing impairments or auditory processing challenges. CAPTCHAs that rely solely on single challenges, such as image recognition or proof-of-work, are becoming ineffective, leading to increasingly complex challenges that negatively impact accessibility for users with disabilities. A more robust and efficient approach is to leverage behavior-based signals, which boost CAPTCHA effectiveness while reducing the barriers faced by people with disabilities. By additionally assessing environmental signals rather than requiring explicit challenges, these methods offer a more seamless and inclusive user experience.

Ensuring that CAPTCHAs are accessible is not just about user convenience. It is also a critical legal obligation supported by both international and regional regulations that aim to promote inclusivity in digital environments. International standards such as the Web Content Accessibility Guidelines (WCAG) provide the framework for accessible design, while region-specific laws like the European Accessibility Act (EAA) ensure these requirements are adhered to.

Some of these guidelines have become legally binding. For instance, the European Accessibility Act mandates that, by June 2025, all digital products and services offered within the EU—including CAPTCHAs—must comply with accessibility standards. This means that companies must adapt or risk facing legal consequences. The drive toward more accessible CAPTCHA systems is not solely about avoiding penalties; it is about creating a digital environment where everyone, regardless of their abilities, can participate on equal footing.

In the following sections, we will explore the legal and regulatory frameworks that govern CAPTCHA accessibility in more detail. We will delve into international standards like WCAG, and examine regional laws including the EAA, Section 508, ADA, and ACA. Each of these frameworks establishes essential requirements that ensure CAPTCHAs are usable by all individuals, thereby fostering a more inclusive digital experience. Let’s dive into these key requirements and explore what they mean for creating effective, accessible CAPTCHA solutions.

Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG), created by the World Wide Web Consortium (W3C), are the key standards for making online content accessible to everyone, including individuals with disabilities. WCAG has evolved over time, from version 2.0 to 2.1, and now 2.2 in 2023, each version addressing new challenges and improving on accessibility requirements. These guidelines are designed to make content accessible by ensuring it can be perceived, operated, understood, and is adaptable. In essence, WCAG helps ensure that everyone can access, navigate, and interact with online content smoothly, regardless of their abilities or the tools they use. CAPTCHAs fall under these guidelines, particularly when it comes to being perceivable and operable.

WCAG outlines success criteria at three levels: A, AA, and AAA. Each of these levels represents a different degree of accessibility, from basic to optimal. Level A focuses on the most fundamental accessibility needs and is considered the minimum standard that must be met to ensure content is accessible to a broad audience. Level AA builds upon these basic requirements, establishing a higher standard that aims to address more common barriers and meet the expectations of a wider group of users. This level is often seen as the standard in many regions, including the European Union. Level AAA represents the highest level of accessibility, striving for an optimal user experience for all, including individuals with more specific or severe accessibility needs. To achieve AAA compliance, all success criteria from levels A, AA, and AAA must be fulfilled, ensuring that content is accessible to the greatest extent possible.

Traditional CAPTCHA methods, like distorted text or image-based challenges, often fail to meet these accessibility criteria, especially at higher levels of compliance. The W3C's draft "Inaccessibility of CAPTCHA" outlines the barriers that traditional CAPTCHA systems create for users with disabilities. It highlights the limitations of existing methods, such as distorted text and audio prompts, and emphasizes the need for more accessible and inclusive alternatives. The following requirements are crucial for ensuring a CAPTCHA complies with WCAG standards:

• Provide text explanations of its purpose and alternative formats like audio or visual options to support different sensory needs.
• Ensure CAPTCHAs are fully navigable and functional using a keyboard, supporting users with mobility impairments.
• Provide flexible or extended timing options to accommodate users who may struggle with time-limited CAPTCHAs.

These criteria aim to ensure that any CAPTCHA is accessible by providing alternatives that accommodate individuals with visual, auditory, motor, or cognitive impairments. WCAG does not explicitly state that multiple presentation modes are a "recommendation", it is implied that providing alternative options is part of meeting accessibility standards.

European Accessibility Act (EAA)

The European Accessibility Act (EAA) is a significant legislative initiative aimed at enhancing accessibility across a wide range of digital and physical products and services within the EU. Drawing inspiration from the principles set out in the 2008 UN Convention on the Rights of Persons with Disabilities, the EAA aims to ensure that individuals with disabilities have equal access to the technologies and services that are shaping the modern world. Enacted as EU Directive 2019/882, the EAA embodies a growing commitment across the European Union to foster digital inclusivity, extending its reach from public services to the private sector.

By June 28, 2025, the EAA will enforce strict accessibility standards for numerous domains, including e-commerce, telecommunications, financial services, and public transportation. This broad scope also extends to CAPTCHAs, ensuring they are developed and implemented in line with accessibility best practices, making sure no user is left behind. The EAA's focus on accessibility means that CAPTCHA systems must comply with established guidelines such as the Web Content Accessibility Guidelines (WCAG), requiring the use of alternative formats like audio, visual, or proof-of-work challenges to accommodate users with diverse needs.

While the EAA establishes broad requirements for accessibility, it does not dictate specific technical implementations for CAPTCHAs. Instead, it aligns with WCAG's approach, which emphasizes flexibility in achieving accessibility standards. For CAPTCHAs, this means offering multiple challenge formats, including audio alternatives for visual challenges, ensuring users of all abilities can engage effectively. Integrating these alternatives is crucial to avoid common pitfalls, such as relying solely on one type of challenge, which can lead to significant barriers for users with disabilities.

The EAA also indirectly encourages innovation in CAPTCHA technologies by emphasizing the importance of seamless and accessible user experiences. Traditional CAPTCHA systems, which may combine various challenge types like visual and auditory tests, often fail to achieve both security and accessibility. Instead, modern approaches, including behavioral CAPTCHAs, are emerging as more suitable alternatives, offering effective bot prevention while ensuring accessibility and usability for all users.

It is crucial for website administrators, product developers, and digital service providers to proactively prepare for compliance to meet the regulatory accessibility requirements. Adopting accessible CAPTCHA solutions not only helps avoid legal consequences but also contributes to creating an inclusive digital environment where users of all abilities are treated with equal importance. Complying with the EAA goes beyond fulfilling a legal requirement. It provides businesses with a chance to foster inclusivity, enrich customer experiences, and show a commitment to inclusivity for all individuals.

Section 508 of the U.S. Rehabilitation Act

Section 508 of the U.S. Rehabilitation Act mandates that all electronic and information technology used by federal agencies must be accessible to individuals with disabilities. Established to promote inclusivity, it ensures that people with disabilities have equal access to digital services, reflecting the broader goal of enabling full participation in government services for everyone. This law, significantly amended over the years, focuses on eliminating barriers in technology that may hinder users with disabilities.

A key implication of Section 508 is its impact on CAPTCHA implementation for federal websites. Traditional CAPTCHAs, which rely solely on visual verification, are not sufficient under this law. CAPTCHAs must be accessible to individuals with visual, auditory, motor, and cognitive impairments, accommodating those who use assistive technologies like screen readers or alternative input devices. To comply with Section 508, CAPTCHA solutions must provide alternatives, such as audio prompts or other accessible formats, ensuring that no user faces undue difficulty while interacting with government websites.

Section 508's requirements align closely with the Web Content Accessibility Guidelines (WCAG) 2.0 Level AA standards, which offer a comprehensive framework for making web content accessible. This alignment emphasizes flexibility, urging federal websites to adopt diverse CAPTCHA solutions that meet the needs of users with varying abilities. Instead of relying solely on a single challenge type, a multi-faceted approach that includes options like audio prompts or behavioral cues is essential for providing an inclusive experience.

In addition, Section 508 pushes innovation in CAPTCHA technology by encouraging developers to replace outdated, one-dimensional methods with more versatile solutions. Behavioral CAPTCHAs, for example, are emerging as a user-friendly alternative that offers robust security while eliminating accessibility barriers. Furthermore, Section 508 represents a core commitment to digital equity, ensuring that digital services are accessible to all individuals, regardless of their abilities. Compliance with these guidelines fosters an inclusive online environment where user experience is enhanced, security is upheld, and values of fairness and equal opportunity are prioritized.

Americans with Disabilities Act (ADA)

The Americans with Disabilities Act (ADA), passed in 1990, is a cornerstone of civil rights legislation aimed at eliminating discrimination against people with disabilities. Initially, it focused on ensuring access to public spaces, employment, and transportation, but it has since grown to encompass the digital world, recognizing how vital technology is in our daily lives. Recent court rulings have emphasized this progression, confirming that websites are public accommodations and must be accessible to all. For businesses, this elevates digital accessibility to be just as crucial as physical accessibility.

Creating accessible CAPTCHAs is a key part of ADA compliance, ensuring that everyone, regardless of ability, can complete verification tasks without difficulty. Many current CAPTCHAs, which often rely on recognizing distorted letters or clicking on specific images, can unintentionally create barriers for individuals with visual or cognitive impairments. To fully meet ADA standards, verification tools need to go beyond basic visual or audio challenges. Innovative approaches like behavioral analysis or interactive question-based challenges can make verification processes more inclusive, ensuring everyone can participate without unnecessary obstacles.

Complementing the Web Content Accessibility Guidelines (WCAG), the ADA provides a foundational legal framework for accessible online content. By following WCAG, companies can design CAPTCHAs that meet diverse needs, providing options in visual, auditory, and alternative formats so users with different challenges can easily verify their identity. This isn't just about meeting legal requirements; it's about building a digital space where everyone, regardless of ability, feels welcome and empowered to engage.

Implementing ADA-compliant CAPTCHAs represents a move towards embracing an inclusive and user-friendly digital landscape. This effort goes beyond merely addressing legal risks and demonstrates a genuine commitment to fostering an accessible and equitable experience for all users. Beyond compliance, it aims to allow all users to engage with digital platforms, ensuring they can participate, collaborate, and achieve their goals without barriers.

Accessible Canada Act (ACA)

The Accessible Canada Act (ACA), enacted in 2019, aims to make Canada barrier-free by 2040. This important piece of legislation is focused on ensuring that all individuals, regardless of ability, can participate fully in Canadian society. The ACA targets barriers in physical spaces, digital environments, employment, transportation, and the delivery of goods and services, promoting equal opportunities for everyone.

In the digital realm, ACA places a strong emphasis on making online content accessible, which includes ensuring that verification methods, such as CAPTCHAs, are usable by all individuals. Traditional CAPTCHAs that rely on visual or auditory challenges can be especially difficult for people with disabilities, including those with visual impairments, hearing difficulties, or cognitive challenges. The ACA encourages the development of accessible CAPTCHAs by promoting solutions that are flexible and inclusive, such as behavior-based verification methods or straightforward question-based challenges that do not depend solely on sensory input.

The ACA aligns with the Web Content Accessibility Guidelines (WCAG), which provide a framework for making web content more accessible for people with disabilities. By adhering to these guidelines, developers can ensure that their CAPTCHAs and other online features are accessible to all users, promoting equal access to digital resources and services. This commitment goes beyond compliance; it reflects the core Canadian values of equity and inclusion.

For businesses operating in Canada or providing services to Canadian residents, complying with the ACA is both a regulatory necessity and an opportunity to lead in social responsibility. Accessible CAPTCHAs are one way to reduce barriers, making digital spaces more welcoming and easier to navigate for all users. By fostering an inclusive digital environment, businesses are not only helping to achieve the ACA's goal of a barrier-free Canada but also demonstrating their dedication to serving every member of society effectively.

As Canada works towards achieving a barrier-free society by 2040, embracing the principles of the ACA will be instrumental in building a digital world that welcomes everyone. Whether it is through adopting accessible verification tools or enhancing overall website accessibility, the ACA provides a clear roadmap for creating an inclusive future, ensuring that all Canadians have equitable access to participate, interact, and thrive in the digital age.

Reviewing Accessible CAPTCHA Solutions

We've seen how traditional CAPTCHA types, including text-based, image-based, and audio challenges, create significant barriers for people with disabilities. Solutions like Google reCAPTCHA and hCaptcha have made efforts to improve, but challenges remain in finding the right balance between accessibility, security, and privacy. Even with these advancements, CAPTCHAs can still be difficult for many users. Google's primary recommendation for those who struggle is to simply reload for a new one, as indicated in their guidance:

Don’t worry. Some CAPTCHAs are hard. Just click the reload button next to the image to get another one.

— reCAPTCHA Help

While this provides an option, it does little to address the underlying accessibility issue for users who consistently find CAPTCHAs challenging. Now, let’s explore how modern CAPTCHA solutions are tackling these issues, aiming to create a more inclusive internet that doesn’t compromise on security.

hCaptcha Accessibility

hCaptcha is a popular alternative to Google’s reCAPTCHA. However, it still poses accessibility challenges, particularly because it tends to rely heavily on image recognition tasks. Users are asked to select specific objects from a series of images, which, as previously discussed, can be a difficult task for users with visual impairments.

hCaptcha no longer supports traditional audio challenges due to concerns about accessibility and reduced effectiveness against automated attacks. Instead, it offers text-based challenges and an accessibility token to better accommodate users with disabilities. The text-based challenge provides a non-visual task, while the token allows users to bypass challenges entirely. Although these measures enhance inclusivity, they are inherently easier for automated systems to circumvent. To maintain robust security, it is essential to use these solutions alongside other verification signals.

reCAPTCHA Accessibility

Google reCAPTCHA has evolved significantly from its initial version to the current versions, v2 and v3. The earlier version, reCAPTCHA v1, relied on distorted text challenges that users had to decipher, which proved effective at the time. However, as bots have become more sophisticated, this approach has become largely obsolete. In the following, we explore the currently active versions reCAPTCHA v2 and v3, which focus on using behavioral signals and scoring mechanisms to improve both security and user experience, while also addressing privacy and accessibility challenges.

With reCAPTCHA v2, Google aimed to simplify verification by introducing the well-known "I am not a robot" checkbox. This version used behavioral signals to distinguish humans from bots, which helped improve the user experience. However, when more validation was needed, it often reverted to image-based challenges like identifying traffic lights, creating barriers for users with visual or cognitive impairments. Additionally, reCAPTCHA v2 collected user interaction data and used cookies for session tracking, raising privacy concerns. Despite these improvements, reCAPTCHA v2 still fell short of fully addressing accessibility and privacy needs.

With reCAPTCHA v3, Google attempted to make the user experience more seamless by scoring users based on their behavior to decide whether they are human. This version is often invisible to the user, which helps alleviate many accessibility concerns. However, reCAPTCHA v3 also presents privacy concerns and can be unpredictable, leading to poor user experience for some, especially for those whose behaviors don’t fit Google’s model of a "typical" user.
