guideline: Enough Time
Allow enough time to read and use content.
2.2.1 Timing Adjustable
Time limits must be avoided unless essential for the task (e.g. exams, auctions). If time limits are used, it must be possible to turn them off, adjust them to at least 10× the default, or extend them by at least 10×.
2.2.2 Pause, Stop, Hide
If content moves, scrolls, blinks, or updates automatically for more than 5 seconds, it must be possible to pause it, stop it, or hide it.
2.2.3 No Timing
Content must not include time limits for reading or interaction, unless it’s part of a live event or time-based activity (e.g. auctions, broadcasts).
2.2.4 Interruptions
Interruptions (like pop-ups, alerts, or notifications) must be able to be delayed or suppressed, and controlled, except in emergencies (e.g. critical system warnings).
2.2.5 Re-authenticating
When (re-)authentication is required (e.g. after session timeout), all previously entered data must be preserved so the task can continue without starting over.
2.2.6 Timeouts
If inactivity could lead to data loss, a clear warning must be shown before the timeout, with enough time to react, and including an option to extend the session.
