Does the PIN entry on Nitrokey 3 have unlimited attempts?

Hi. I’ve just read this page on how to setup PINs on the Nitrokey. It states

The PIN has retry counter of 8 attempts. After 8 attempts, it is locked and the FIDO feature needs to be reset change the PIN. To prevent accidental lock of the PIN, the device needs to be unplugged and replugged every 3 attempts.

to me this reads like you have infinite attempts at entering the PIN if you just re-plug the Nitrokey every 3 attempts. If this is true that would be very bad since someone could brute-force the PIN and get access to the secrets that way.

Please clarify what this means and update the docs if this is not the case.

No, the FIDO2 and GPG PINs will eventually lock. FIDO2 only has a protection against accidental blocking it and needs to be replugged for another set of tries until all are exhausted.
