IT does? Damn, didn’t know - my bad. Where I’m from IT doesn’t have the keys, and the people that do have the keys know better than to try entering people’s dorms, unless it’s really something critical. Wifi doesn’t qualify.

Some WiFi routers can be configured to not advertise their network; annoying because you’ll have to manually enter the network information on every device, but it might keep you from getting caught.

Just name the network something like Samsung S20 Personal Hotspot. They’re not gonna look into why a student created a Hotspot with their phone.

Or, shit - lock the fucking door.
