Session Warning That Gives Users Less Than 20 Seconds to Respond

2.2.1 — Timing Adjustable

Scenario

Setting

A nonprofit's donation form

What’s wrong

Warning shown but with <20s to respond, or requiring complex re-auth as the "simple action".

Example

setTimeout(() => logOut(), 60000); // no warning

Why it matters

People who read, type, or move slowly, including many screen-reader users.

How to test

Time the warning before session expiry: it must appear at least 20 seconds before the timeout, giving a simple way to extend — less time 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 nonprofit's donation form, this barrier is gone for people who read — they get the same result as anyone else here.

Who is affected

People who read, type, or move slowly, including many screen-reader users.
