LockScreenAutoStartOnlineReauth

On the lock screen users have an option to open an online re-authentication window and use it for authentication process to re-enter their session. This policy can be used to automatically open the window if online re-authentication is required. If the policy is set to Enabled and online re-authentication is required, the online re-authentication window is opened automatically. If the policy is set to Disabled or unset, the online re-authentication window has to be opened manually. Online re-authentication can become required for a number of reasons, such as password change, but it can be also enforced by certain policies such as GaiaLockScreenOfflineSigninTimeLimitDays or SamlLockScreenOfflineSigninTimeLimitDays.
