I’m still terrified how normal people are going to navigate being locked out of their email account because their device that was their passkey is no longer accessible and there’s no backup solution to restore access.

I’ve similar issues even in a lower level with LastPass where it won’t even let you enter your two factor if it doesn’t recognize where you’re coming from but then you have to be connected to your email, but your email password is stored in LastPass. There is a real possibility of being locked out at all devices at the same time and not being able to get in to the first one.
