What kind of idiot would lock all of his systems down to allow access only via a specific SSH key stored on a smartcard (Yubikey), write the PIN unlock code for that smartcard on a piece of paper stored somewhere safe, and then head on a work trip where he **promptly** enters the wrong PIN three times and locks himself out of everything. The answer, is me. So much for spending my hotel evenings screwing around with my home server… #yubikey #homelab
