Captcha

Impact: Major

Users mainly impacted: Blind, visually impaired, mentally and cognitively impaired.

RGAA criteria: Criterion 1.4 - Criterion 1.5

Explanation

In the case of test images (Captcha), the alternative must be filled in so that the user can understand the nature and role of the image.

For example, alt="enter the code in the image".

This mechanism will have to be completed by an alternative method allowing the user to retrieve the code in order to continue. Example, an image CAPTCHA can be associated with an audio player.
