Make authentication accessible

Traditional CAPTCHAs that require identifying distorted text or images are particularly problematic for users with visual impairments and cognitive disabilities. Instead, offer accessible alternatives such as email magic links, one-time passcodes sent via SMS, or modern passkeys that use device biometrics.

For password-based systems, support copy-paste functionality rather than blocking it for "security reasons." This feature is essential for people using password managers or assistive technologies. Consider implementing WebAuthn/FIDO2 standards that allow authentication through fingerprints, facial recognition, or security keys, which reduce reliance on memory while enhancing security.
