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

I've never had a need to use a Yubikey, but is that the button which spews gibberish into DMs? I've seen that a lot at work on Teams lol

Sound about right. A YubiKey will print a one-time password when touched, by default.

Do you know if this functionality can be turned off? I've been stung by the 'gibberish' once or twice but never enough to dive into the docs for it :)

Yes, you can configure what happens when you touch the button.

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.
