Enforce a limited session lifetime for all policies

Session lifetime determines the maximum idle time of an end user's sign-on session to Okta. Lowering this value decreases the risk of malicious third party access to a user's applications from an active session.

The maximum time allowed time for this setting is 90 days. The default session lifetime is 2 hours. On the end-user dashboard, a countdown timer appears at the 5-minute mark of remaining session time.
