THE ACCESSIBILITY PROBLEM WITH AUTHENTICATION METHODS LIKE CAPTCHA

Summary from the TLDR Design newsletter

CAPTCHAs were designed to block bots, but they now block people more often, especially users with disabilities. As tests grow more complex, they remain ineffective (bots routinely solve them) while becoming inaccessible for those using screen readers, assistive tech, or with visual, auditory, motor, or cognitive impairments. Developers are encouraged to move on to better options like MFA with autofill, single sign-on, magic links, or invisible checks such as Cloudflare Turnstile, and to offer multiple accessible authentication choices tested with real users.
