Not secure at all. You can be coerced physically to unlock something private/secure. Security should always be a combination of something you know and something you have (2FA).
Additionally, requiring a central authority to manage security is just _asking_ for trouble. Passwords work because of how de-centralized it is. Biometrics and physical-only tokens will fail the minute people realize they can just steal that data and use it to unlock everything centrally.
What we need are better tools to manage passwords in a more transparent way.
