Hello,

I'm getting an issue while I'm trying to dump my pico keys on Windows. I'm running the Python script as admin and the PIN is correct. Target is Pico 2 W.

Here is the output with the correct PIN:

C:\Users\me\Downloads\pico-fido-main\tools>python pico-fido-tool.py -p 0000 backup save myfile.txt

    raise CtapError(status)
fido2.ctap.CtapError: CTAP error: 0x33 - PIN_AUTH_INVALID

Here is another test with an incorrect PIN:

This is not meant to backup the keys. This tool is for backing up the key encryption key for RP2040, since they do not have OTP.
This command succeeds if previously you enabled secure key.
