What if the user is trying to login via a device different from the first one?
- tialaramex 8y agoI can't tell what "a device" means here. If you mean "what it I only used Security Key A to register, but now I want to sign in with Security Key B?" the answer is that you can't, that's the wrong key. Register all the keys you want to use. If you meant what if I registered with my Pixel phone and now want to sign in on my Windows PC, that just works fine. The client "state" lives in the Security Key (actually there is no state whatsoever in affordable designs), it's very clever cryptography.
