> Let's assume that they were all Passkeys.

Lets assume I put all the effort to explain.

I will give you a better example.

- Lets say you have a google account with pixel phone

- You are using it and added 1000 passkeys

- All are synced to your Google account

- Destroy and Get a new phone. Login to your google account with recovery code.

- All your passkeys are in your phone again.

There are plans in fidoalliance.org to make it portable. Pretty sure you are still not going to move to it.
