- 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
<!-- Login requires solving an image CAPTCHA, no alternative -->Why it matters
People with cognitive disabilities and anyone who depends on password managers or paste.
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.
<!-- Login uses email + password, or a passkey, with no puzzle/transcription step -->Authentication can't rely solely on solving a puzzle or transcription task with no cognitive-function-test alternative.
Outcome
On a streaming music app's search results, this barrier is gone for people with cognitive disabilities and anyone who depends on password managers or paste — they reach the same outcome without extra effort.
Who is affected
People with cognitive disabilities and anyone who depends on password managers or paste.
