To add to this, I also want the ability to move "ecosystem" - passkeys are "platform-backed", meaning Chrome on iOS is "iOS" as far as passkeys are concerned, and you are stuck in the iOS keychain. I want to see proper migration paths between iOS, Android, Linux, Windows, Mac, BSD etc - so that there is no platform lock-in or inertia that prevents you leaving one platform for another, and quickly (in under 30 seconds) moving everything across. At a time when competition authorities are clamping down hard on platform dominance, self-preferencing and lock-in, passkeys risks becoming a pain point if there isn't proper, genuine, portability. I'm also not keen on the lack of self-sovereignty of passkeys as you suggest - this feels like a "by the back door" way to force everyone into using "Sign in with X" type federated login. When your cloud account is locked out by Google AI, you want to be able to sign in to your other services! People have already started to discover the risks of Oauth type login when their bigtech company locks them out.
