alt Hacker NewsWhat if I lose all my apple devices? House break-in and they steal my mac and my phone?
You're basically fucked even if you buy a new one because you need one of the other two to log in.

No technology in the world can protect you against every threat model and unlikely scenario.
What if the robber hits you in the head and you get brain damage and forget your password?

Then you'll login to your Apple iCloud account using your password.
Passkeys are just passwords that require a password manager; you can't login to a password manager without something outside the password manager, usually a password. (That's why they call it "LassPass" and "1Password"; there's one last password you'll still have to maintain.)
No password manager tries to get you to login with a passkey without setting a password, for precisely that reason. Apple, Google, and Microsoft do invite you to login to their password managers via passkey, because it's convenient and unphishable, but they always also allow you to login via password (or "backup codes", which are just backup passwords).
