I can try.
My yubikey has an edit pin and a reset/admin pin
When I configured my key I used the edit pin to perform all actions and can use the reset/admin pin to reset the edit PIN.
When I had setup my yubikey to decrypt the LUKS partition on my Debian system I had to set up a PIN/Passcode that I put in before pressing the “button” on my yubikey. This PIN/Passcode was different than the PIN I used when setting up the yubikey. (Even though it’s different I’m pretty sure it’s similar enough for comparison sake, but this is where the potential for my not properly and completely understanding what’s going on may be an issue)
Yes I know yubikey-luks is different than smartcard-key-luks, but I think they are similar; though I could be wrong.
And yes my experience, is likely different than yours, I’m just asking questions to see if my experience was similar enough to help.
