- Success Criterion 2.2.1
- Conformance level A
Timeout Adjustment Option Set Below the Required 10x Default
2.2.1 — Timing Adjustable
Scenario
Setting
A food-delivery app's order-tracking screen
What’s wrong
Adjust option offering less than 10× the default.
Example
setTimeout(() => logOut(), 60000); // no warningWhy it matters
People who read, type, or move slowly, including many screen-reader users.
How to test
Check any 'adjust the timeout' setting: it must let the user set the limit to at least 10x the default — a smaller multiplier fails.
How to fix
The time limit must be removable or adjustable (to at least 10x) before it starts, or extendable via a warning giving at least 20 seconds to respond with a simple action. setTimeout(() => showExtendSessionPrompt(), 55000); Users need a warning and a way to extend a time limit before it expires, unless the limit is essential (e.g. an auction).
Outcome
On a food-delivery app's order-tracking screen, this barrier is gone for people who read — they can finish what they came here to do.
Who is affected
People who read, type, or move slowly, including many screen-reader users.
