Unfortunately, many services don't allow you to register multiple passkeys, so having a backup key that is stored somewhere safe is simply not an option.

- chipsrafferty 1y agoThat's why you have multiple passkeys that have the same key. It's a physical backup, not a software backup.
- crote 1y ago... at which point you lose the whole "something you have" part of 2FA. If they all have the same key, it is impossible to distinguish between individual copies, so the compromise of a single copy is impossible to detect. Additionally, you can't revoke a single copy: you are now forced to revoke all of them at once.
- rcxdude 1y agoIs that what you have set up? Can you describe how you do it in more detail? I'm looking for an option like this but everything I've found seems to suggest it's not possible (or at the very least wildly impractical). I'm looking for something where it's at least possible to make a physical backup that's still relatively secure.
- dfedbeef 1y agoYou only need multiple on your recovery email. Unless you're using Yahoo or running your own email server, this is an option.
- dfedbeef 1y agoIt might be possible to set it up on a home server idk. I would rather waste my time on other stupid things.
