Ask HN: Is Fingerprint Authentication in phones a good idea?
1 comments
As a sole form of authentication, no, absolutely no. Fingerprints have a lot of disadvantages, even relative to other biometrics. Extremely easy to steal/spoof, not actually unique, and impossible to revoke on account compromise.
You can make the argument that they're mildly useful in 2 (or more) factor auth-- probability that someone has both obtained your password AND lifted your prints is somewhat less likely than either alone.

What if a Fingerprint Phisher app acquired a young adult's fingerprint when he/she was young and stupid? How can that young adult change his/her fingerprint so it cannot be used once he/she grow up to be a rich professional?
I never I understood what is good news in this.
