    SSH keys are a public and private keys that you can use to sign and verify messages back and forth. passkeys are literally the same thing. the only difference is passkeys are unique per site and you store them in an encrypted file that you only need a single password to access vs an ssh key the passwords are per key pair.

    essentially the passkey is used to sign a bit of metadata and then the service verifies that metadata matches the user via the public key on file in their system. but otherwise they’re functionally the same thing as ssh keys.
