Timeout mechanism is not keyboard accessible
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.
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.
When a timeout warning and mechanism to extend a session are not keyboard operable, the requirement is not met.
Fix this issue by ensuring the time extension option is keyboard operable.
