Update from https://support.nitrokey.com/t/will-fido2-also-support-piv/2070/3:
I am also still looking for a Nitrokey that supports a password-less login on a macOS.
And as far as I know password less login on macOS should work with the Nitrokey Pro and OpenSCToken:
Is the NitroKey Pro 2 supported? · Issue #13 · frankmorgner/OpenSCToken · GitHub
But until now, I didn’t got it working:
TKAuthenticationHintsProvider error -11 · Issue #14 · frankmorgner/OpenSCToken · GitHub
I would be very keen if anybody could give me a hint why this is not working.
