GAT+ can report on the active count of 2FA codes within the security tab of User Audit. This reflects the active number of 2FA codes which are available for each user.
In the Configuration section under Alarms, create an alarm for 2FA codes being used by your users. In the example below any 2FA codes being used by users from /Marketing OU will trigger an alarm to the super admin.
