Does it only support ecdsa? Surprised they don't use ed25519 in their example.

Edit: nope, seems ed25519 supported too https://manpages.ubuntu.com/manpages/focal/en/man1/ssh-keyge... although internet seems to suggest hardware support is far more limited. Tried generating one on MacOS and indeed my Yubikey seems unsupported.

Unfortunately, you can't use Ed25519 keys unless you have the latest/newest model(s) of Yubikey and that Yubikey came with at least a specific firmware version (5.2.3, IIRC).
