FIDO login with SFTP servers

I use a FIDO key to log into my server and it would be lovely to be able to log in with my FIDO key instead of relying on OpenPGP.
It is supported with OpenSSH so all you need to do is figure out how to communicate with the key (probs with windows hello).

Please see FIDO Support?.

I posted a tutorial how to do this using PuTTY-CAC in this topic:
