Catalina - Disable Login to Other User's Active and Locked Sessions
Information
The ability to log in to another user's active or locked session _MUST_ be disabled. macOS has a privilege that can be granted to any user that will allow that user to unlock active user's sessions. Disabling the admins and/or user's ability to log into another user's active andlocked session prevents unauthorized persons from viewing potentially sensitive and/or personal information.
