This. This is why I am happy to use security keys at work (if I lose all of them, there is a way to be issued new ones using a manual identity verification method plus another person's security keys ) but I've been too nervous to put them on my own account.

Also, if you are adding support for security keys in your app, please make sure there are ways to add and remove multiple keys (so I can have backups, and per-device keys).
