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.

Solution

[source,bash]
----
/usr/bin/security authorizationdb write system.login.screensaver "use-login-window-ui"
