Unlock any door, box, TC, etc. as admin?

I remember if you were an admin or used the vanish command you could open any locked door, box, and tc or auth yourself to any tc.

Was that a different plugin or did they change admin powers over the years ?

You still can

I'm admin, inside vanish mode and I cannot auth past a keylock or open a door.

No idea why. 

There's a built-in command that you can use, I believe it's "ent unlock"
Different features might be under different permissions.

Admin abuse

I just remember a few years ago you were able to just walk up and open doors or auth to TC without any extra plugins or commands. I suppose they just changed it? 

-Is badmin a plugin? 

-What is the most effective way to be able to admininistrate, while keeping a watchful eye without having to be vanished/noclip the entire time, while checking TC activity, and boxes with locks ?
