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.

If you use Safari, they're locked to all of the devices on your iCloud account, not to a single device.

I login to 1Password on another device and all passkeys are there, and usable.

The OSes I use where that works fine:

- Android - Windows - Linux - macOS - iOS
