I’ve been using a Nitrokey FIDO2 for a few months. Just now, one of the sites (WordPress) has converted from U2F to FIDO2. Where I previously only needed to touch the Nitrokey to gain access (as a second factor), now a PIN is requested.
I’m pretty sure I remember this PIN (which I might have set on initialization, but never used since), but it isn’t accepted. Finally I’m now get the warning that the key will be “locked” if I enter the wrong PIN again.
How do I fix this? Full reset is an option, but will this clear the issue or is “locked” to be taken literally, meaning “key disabled permanently”?
