Google blocking you doesn't affect passkeys; you must be thinking of things like "Sign in with Google" where you must sign into Google to sign into another website. The best thing about passkeys that's not available to traditional passwords is that you can have multiple passkeys that are equally valid, unlike the case with passwords where you can have but one single valid password. As someone who uses both Android and iOS frequently, I can set up passkeys on an Android and then an iPhone without needing to trust anyone (not Google, not Apple) to sync them. With that understanding I can address your concerns: * If one phone is lost, I can use the other passkey to revoke that particular passkey. * Even if Google blocks me so completely that my Android is remotely bricked by them, the other passkey still works. * Migrating from one provider to another is trivial: I might be belaboring the point but you do not need the exact key material to be migrated, you only need a new equally valid passkey.
