Rule
CAPTCHA tests MUST have alternate forms using different input modalities, such as visual task and an audio task.
Background
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:
- Providing more than two modalities of CAPTCHAs
- Providing access to a human customer service representative who can bypass CAPTCHA
- 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.
