Visual CAPTCHA Required With No Non-Visual Alternative
3.3.8 — Accessible Authentication (Minimum)
Scenario
Setting
A food-delivery app's order-tracking screen
What’s wrong
Visual CAPTCHAs (distorted text) required with no object-recognition-exempt alternative or non-cognitive alternative path.
Example
Consider a food-delivery app's order-tracking screen: visual CAPTCHAs (distorted text) required with no object-recognition-exempt alternative or non-cognitive alternative path.
Why it matters
People with cognitive disabilities and anyone who depends on password managers or paste. The practical effect on a food-delivery app's order-tracking screen: they are blocked from using a password manager.
How to test
Attempt to log in: if a distorted-text visual CAPTCHA is required with no alternative (audio, non-cognitive method), it fails.
How to fix
Login must work with paste and password managers — any cognitive test must have a non-cognitive alternative method.
Outcome
That one change on a food-delivery app's order-tracking screen means they sign in without a memory test.
Who is affected
People with cognitive disabilities and anyone who depends on password managers or paste.
