A software passkey you can copy. Or even store it in a self hosted or cloud based password manager, such as Bitwarden.
A passkey is in summary a private key, so sure you can copy it as many times as you want. But you don't risk getting it stolen while using it because you don't send it for authentication, you just send a message signed by it.
This is how Bitcoin or Nostr work. And same way there are software and hardware wallets for storing Bitcoin private keys, there are hardware passkey devices implementing different standards such as FIDO2.
You can set up multiple passkeys for an account, so that losing access to one of them does not lock you out of the account.
It's clearly a good idea. Nice to see that the world is moving towards trustless and secure authentication as in Bitcoin.
