I think technically you can just register the public key of the passkey and only need it on-hand for login

  Technically i would think so too, but is that how it's implemented? (I legit don't know, but my feeling was always that you had to add them while they're present, especially as there's different passkeys for different sites, to do it offline do you pregenerate 100 keys for each device to assign later?)
