Setting up SSH with a FIDO key

Windows 11

Windows 11 ships with outdated software which means before all, you will need to install the latest version of Win32-OpenSSH which supports FIDO2 flows.

The rest is pretty easy:

  • Generating the key: ssh-keygen -t ed25519-sk -O resident and should output your new public key to ~/.ssh/id_ed25519_sk.pub

Now trying to SSH into something should bring up a window asking you to touch your key to confirm the action.
