Sounds fairly sensible to me

If it's truly sensitive data, encrypting with a unique private key and locking that with a PIN a la FIDO via NFC would be a bit more secure.

One master key leak and everyone is walking around with IDs that give away sensitive data over RFID.

> sensitive data

"Sensitive" data that you already leave on everything you touch.

You leave your DNA everywhere, too, but there are data security and privacy implications of digitizing that data and voluntarily/involuntarily sharing it with others.

"Many passports also contain your computer password. But those are even harder to access. You need a private key that only governments have."

Still reasonable?

If you think of your fingerprint as a "secret", you're wrong. It's more your name. That would be like saying your face is a secret. It's not.

> If you think of your fingerprint as a "secret",

I can unlock my laptop with just a fingerprint. Whether or not we believe this the implementation already exists.

> It's more your name.

I can change my name. Can I change my fingerprints?

> That would be like saying your face is a secret.

I can unlock my phone with my face. Whether or not we believe this the implementation already exists.

> It's not.

Let's discuss the real world and not the ideal fantasy.
