Operable / 2.2 Enough Time
2.2.1Timing Adjustable
Level AIf content imposes a time limit such as auto-logout, let users turn it off, adjust it to at least ten times the default, or extend it after a warning with at least twenty seconds to respond. This matters because users with cognitive or motor disabilities often need more time to read or complete input. Exceptions apply to real-time events, limits that are themselves essential (e.g. an auction), and limits longer than twenty hours.
