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
Yes, that's exactly what it is. I had to get one for work because they wanted everyone to use the MS authenticator app on their (personal) phones. I got the Yubikey instead.
But yeah, gotta watch that you don't accidentally touch it. I had a colleague carry my laptop once and was surprised to find some interesting additions to my code.
