I use gpg-agent, but I agree it is often a pain. I will probably switch to U2F + SSH once more servers have OpenSSH 8.2.

Do you know if this already works with GitHub?

It does not. From an `ssh -vvv [email protected] -i <path/to/sk key>` session:

    debug1: Next authentication method: publickey
    debug1: Offering public key: <path redacted> ED25519-SK SHA256:<pubkey redacted> explicit authenticator
    debug3: send packet: type 50
    debug2: we sent a publickey packet, wait for reply
    debug3: receive packet: type 51
    debug1: Authentications that can continue: publickey

Packet type 51 is SSH_MSG_USERAUTH_FAILURE (see https://www.ietf.org/rfc/rfc4250.html#section-4.1.2).

I don't, and I doubt it (there would be an announcement), but it will be great when it does.
