google didn’t come up with passkeys. It’s an idea that originated from the FIDO Alliance (of which google is A MEMBER).

Apple introduced iCloud Keychain / Passkey early 2021 at WWDC21. At the time Apple was working with FIDO Alliance to make Passkeys an official thing.

I doubt they saw your idea, and anyway if they didn’t copy no one would support it.

That’s cool. Microsoft added in biometrics though right? Biometrics in general seem like a terrible security risk in any setting. Your idea makes sense to me.
