I recently had a phone with a bunch of passkeys on it die unexpectedly. I didn't spend weeks resetting passkeys. I just logged into things with my hardware token on my keyring until all the sites I cared to use on my phone had fresh passkeys.
Or if my keyring was in the other room, I'd use the passkey on my laptop or desktop.
Most phones are waterproof and if your toilet holds your phone, laptops/desktops, and recovery keys it’ll also take your password vault because it’s an actually a black hole.
I currently have moat passwords synced with firerox. If I lose or break a device currently, I can restore from another, synced, device. If while using passkeys I lose or break my device, then what?
Any of your other devices will still work, as will your recovery codes, for getting a new device synced.
How would that work without a homogenious setup? Won't all devices need to be with Apple or Microsoft (etc)? Or is there a standard/cross platform solution?
