Description
The Tanium Console, when multifactor authentication is enabled, will initiate a session lock based upon the ActivClient or other Smart Card software. By initiating the session lock, the console will be locked and not allow unauthorized access by anyone other than the original user. Although this setting does not apply when multifactor authentication is enabled, it should be explicitly disabled in the event multifactor authentication is ever broken or removed.
