What WCAG 2.2.6 Requires
Visitors must be warned about any user inactivity timeout that could cause loss of data, unless the data is preserved for at least 20 hours after the timeout.
Can AccessBell Test This Automatically?
Not fully. Like most WCAG criteria that depend on meaning or context, this one needs a person to judge. AccessBell's report lists it for manual review rather than marking it pass or fail automatically, so it never gets missed.
How to Test It by Hand
Check whether a warning appears before a session times out, or whether entered data is preserved afterward.
Common Failures
- A banking or account session silently logs the visitor out with no advance warning.
