CAPTCHA has long been a tool to differentiate between humans and bots online, but it creates significant accessibility issues for people with disabilities. While it aims to block spam, the various forms of CAPTCHA—like image classification and audio challenges—often exclude those who rely on assistive technologies. For instance, visually impaired users struggle with distorted text CAPTCHAs because screen readers can't interpret them. Audio CAPTCHAs, despite their intention to provide an alternative, often feature distortions that make them hard to understand for those with hearing difficulties. The challenges posed by CAPTCHA aren't just technical; they impact user experience deeply. A 2023 study found that users collectively wasted over 819 million hours on reCAPTCHA sessions, and bots can now solve these tests with remarkable speed and accuracy—up to 100% in some cases. This raises the question of whether CAPTCHA is even effective, as bots are outperforming humans. Compounding the problem, many users give up after a few failed attempts, with nearly 59% likely to abandon a website if they face cumbersome authentication processes. Moreover, alternatives like hCAPTCHA aim to improve accessibility but often fall short in practice. Users report frustrating experiences, like receiving error messages that force them back to the standard CAPTCHA challenges, which may not be configured to accommodate screen readers. Issues persist with third-party cookies and time-sensitive codes that may expire before users can complete the process. Overall, the complexity and inaccessibility of CAPTCHA and similar authentication methods hinder rather than help genuine users, particularly those with disabilities.
