Usually this means using a password manager, and these days many of them also support WebAuthN in a way not tied to a specific device (or platform/ecosystem).

Sure, if your password vault gets breached then everything is exposed but that's extremely unlikely and you have a lot of work to do in that event regardless. It's an inherent risk to using a password manager: everything is centralized so it's a valuable target.
The point of a second separate factor is to reduce that risk.
