After updating my PureBoot firmware to 18.1 to fix the security issue I was prompted to generate new TOTP/HOTP secrets, and was prompted to enter a Librem Key admin PIN to do this. I had previously changed my PINs from the defaults but the new PINs I had replaced them with did not work (always “wrong PIN” error). So I searched this forum and found a post recommending to OEM Factory Reset the Librem Key to get the default PINs back: Forgot both PINs to my Librem Key
After doing an OEM factory reset I was again prompted to enter a Librem Key admin PIN to update TOTP/HOTP secrets. The default PINs all throw the “wrong PIN” error, as do the old PINs. I am at a loss as to how this is possible - can anyone recommend a way of resetting my PINs, or give some insight in to why the default PINs would not be working after an OEM Factory Reset?
