To guard against lockout, you need to be able to log in from multiple devices. But you don’t need to copy passkeys around to do that! Instead, generate a new one for each device. This is similar to setting up ssh by copying public keys, not private keys. (Or since syncing passkeys usually works within ecosystems, you might just need a passkey per OS.)
