That's all I want to know. How do I restore from a backup? Specifically, a backup that I make to a medium I control, like a piece of paper or a burned CD-R in a safe deposit box. If I could get a good answer to that, I could be onboard. But from the conversations that I am getting here, it looks like only certain managers allow it, and with device attestation, they could be banned at any moment by any website with no recourse.

Isn't this true of any authentication method? It doesn't seem unique to Passkeys.
