User cannot turn off, adjust or extend time

Rule

If there is a session time limit, users MUST be warned before the session ends and MUST be given time to save their data and/or extend the session.

Background

People with disabilities such as blindness, low vision, mobility impairments, and cognitive limitations may require more time to read content or to perform functions such as filling out online forms. If a session has a time limit, it may be difficult or impossible for some users to perform the required action before a time limit occurs. People must have the ability to turn off or extend time limits while interacting with content. Giving people the ability to turn off or extend the time helps ensure that they can complete tasks.

How to Fix

Fix this issue by providing an accessible warning of the timeout and an accessible mechanism to do ONE of the following:

1. Turn off: Allow the user to turn off the time limit before encountering it.
2. Adjust: Allow the user to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting.
3. Extend: Warn the user before time expires, give the user at least 20 seconds to extend the time limit with a simple action (for example, "press the spacebar"), and allow the user to extend the time limit at least ten times.
