Box 1: Set a timeout in the Power Platform admin center.
To enforce users to reauthenticate after a pre-determined period of time, admins can set a session timeout for their individual environments. Users can only remain signed in the application for the duration of session. The application signs out the user when the session expires. Users need to sign in with their credentials to return to customer engagement apps.
