We recently had a small group of laptops stolen. They were student checkout laptops and had wifi disabled. As soon as the theft was discovered I tied them to DEP with a prestage enrollment. One of them re-enrolled a few days ago with the JSS management account. Is there a way I can add a secondary admin account and keep it hidden? I would like to be able to ssh into the computer.
