- Conformance level AA
One-Time Code Split Into Boxes That Reject a Pasted Code
3.3.8 — Accessible Authentication (Minimum)
Scenario
Setting
A photo-sharing app's upload screen
What’s wrong
one-time password (OTP) split into 6 single-character inputs that reject paste of the full code.
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
Copy a one-time code and try to paste it into a split multi-box OTP input: if pasting the full code doesn't work and each box must be typed individually, 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 photo-sharing app's upload screen, this barrier is gone for people with cognitive disabilities and anyone who depends on password managers or paste — they get the same result as anyone else here.
Who is affected
People with cognitive disabilities and anyone who depends on password managers or paste.
