alt Hacker NewsI do it with FIDO2. It's inconvenient when having multiple Yubikeys (I always end up adding the entry manually with ssh-agent), and I have to touch the Yubikey everytime it signs. That makes it very annoying when rebasing a few tens of commits, for instance.
With GPG it just works.
For what it's worth: You can set no-touch-required on a key (it's a generation-time option though).
