What issue are you seeing?

Hi

I have an yubikey where I had previously enabled the pin code feature, but I wanted to disable it and attached
it and asked codex to try to disable the pin. Apparently the only way to disable the pin is to reset all of the credentials on
the yubikey, and therefore codex concluded that a reset was necessary. I managed to stop it before the reset, but I think
it should report that there is no on/off feature for the pin code instead of doing a wipe.

The yubikey is version NFC (5.7.1) [FIDO], and it is attached to my macbook air M2 through an usb-a -> usb-c connector (since M2 air's don't have a built in nfc reader).

The tool codex used is called ykman.

No response

The report provides no file or test entry point. Start by reproducing the request against Codex CLI 0.154.0 and trace the action path that interpreted disabling a PIN as resetting YubiKey credentials. Done means the agent safely handles the request without attempting credential-reset actions, with a regression test covering the behavior.
