Maybe not “magic” but you can get very close to that with “Discoverable Credentials” on a FIDO2 key.

The process for using a discoverable key on a new machine re-imports the relevant public key and private key handle to the new machine when you “ssh-keygen -K”. Its roughly equivalent to copying key material around with a flash drive, but without the need to remember two physical items.
