For a few days now, Firefox has been asking me to enter some “device PIN” whenever I tried to log into any account that requires my Nitrokey FIDO2 key as the second factor (only 2FA, no password-less login). I never set any PIN for the key and don’t know why Firefox asks me for it.
I thought that it might refer to the Windows Hello PIN on my other laptop. Unfortunately, I don’t remember the PIN entirely, so I tried multiple versions of it. None of them worked, and now Firefox says that I need to reset the FIDO2 key because the PIN was entered incorrectly too often.
However, logging in with the FIDO2 stick in LibreWolf still works fine. According to https://update.nitrokey.com the firmware is up-to-date.
Even on https://update.nitrokey.com Firefox asked me to enter “the” PIN.
What should I do? Thank you!
