How to Check Whether Website Security Challenges Have Accessible Alternatives

A CAPTCHA can block legitimate visitors who cannot interpret visual puzzles, hear audio prompts, or use a mouse. Repeated challenges can also frustrate people using assistive technology or shared devices.

What to check

Test the full challenge with keyboard-only navigation, screen readers, zoom, and common assistive settings. Check focus order, instructions, error recovery, time limits, and whether a non-puzzle verification path exists.

Recommended next step

Choose proportionate abuse controls that provide an accessible alternative and do not rely on one sensory task. Monitor false positives and provide a clear route to support when an automated challenge cannot be completed.
