Yubico Forum

Hi,

since yesterday I'm a new prod owner of a Yubikey 4 and I've got directly a question where I've found no answer in google.
I remember that when I've made my first steps in the Yubikey configuration that the PIN retry counter was 3 3 3.
Now, after a lot of configuration changes and some blocked PINs and PUKs the numbers are on 3 0 3.
I've followed the instructions here (https://developers.yubico.com/yubico-pi ... ction.html) to reset PIN and PUK but that have no influence on the middle number. Can someone explain me which number is standing for what?

The NEO will show 3 3 3, while the YubiKey 4 will show 3 0 3. This is expected behavior. The second number isn't actually used anywhere.

======================================================

PIN retry counter
This field saves how many tries still are left to enter the right PIN. They are decremented whenever a wrong PIN is entered. They are reset whenever a correct AdminPIN is entered. The first and second PIN are for the standard PIN. gpg makes sure that the two numbers are synchronized. The second PIN is only required due to peculiarities of the ISO-7816 standard; gpg tries to keep this PIN in sync with the first PIN. The third PIN represents the retry counter for the AdminPIN.
