WCAG 2.2.6: Timeouts
WCAG 2.2.6 requires that users are warned about data loss due to inactivity timeouts, and that any such timeout lasts at least 20 hours unless the data is preserved. This protects users with cognitive disabilities, motor impairments, and others who need more time to complete tasks.
