- Success Criterion 3.3.8
- Conformance level AA
Login PIN Entered Only via a Randomized On-Screen Keypad
3.3.8 — Accessible Authentication (Minimum)
Scenario
Setting
A streaming music app's search results
What’s wrong
Log-in flows requiring memorized PIN entry on a randomized on-screen keypad (blocks assistive entry) with no alternative method.
Example
Here's a real case from a streaming music app's search results: log-in flows requiring memorized PIN entry on a randomized on-screen keypad (blocks assistive entry) with no alternative method.
Why it matters
People with cognitive disabilities and anyone who depends on password managers or paste. In this case (a streaming music app's search results), they get locked out of the account entirely.
How to test
Try to complete a login requiring a memorized PIN entered via a randomized on-screen keypad: if this blocks assistive input methods with no alternative, it fails.
How to fix
Login must work with paste and password managers — any cognitive test must have a non-cognitive alternative method.
Outcome
Once corrected, a streaming music app's search results lets them complete authentication without getting stuck.
Who is affected
People with cognitive disabilities and anyone who depends on password managers or paste.
