Got a used business laptop and found a recessed dongle in it. The original owner says they have no clue, that it’s been in there since they got it. There’s no way a dongle is keeping this thing running, is there? I’ve already swapped the OS, if that matters at all

Update: yubikey! Thank you all for the information, I’m definitely still learning
