frustrating things I learned the last 2 days
#Yubikeys gpg-card default pin is 123456, admin pin is 12345678. if you enter the admin key 3 times wrong, you need to factory reset the gpg-card feature

If you use pinentry loopback (CLI-input), it wont tell you if you need to enter the user or admin pin. #gnome console doesnt work reliably with the loopback pinentry, the loopback itself is very wonky.
