CAPTCHA tests MUST have alternate forms using different input modalities, such as visual task and an audio task.


CAPTCHAs are a controversial topic in the accessibility community. Every type of CAPTCHA will be unsolvable by users with certain disabilities. Providing two different forms of CAPTCHA on a given site ensures that most people with disabilities will find a form they can use. Because some users with disabilities will still not be able to access sites that use two different CAPTCHA techniques, additional recommended steps include:

  1. Providing more than two modalities of CAPTCHAs
  2. Providing access to a human customer service representative who can bypass CAPTCHA
  3. Not requiring CAPTCHAs for authorized users

How to Fix

Fix this issue by including an additional CAPTCHA option that relies on using a sense other than sight.
