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 providing alternative text that describes the purpose of the CAPTCHA, such as "Type the word in the image" or "Type the letters spoken in the audio"
