Biometrics is by no means perfect and it's definitely not safe for online services. It can be an extra layer of security, at best. How to hack someone relying only on biometrics: - Craft malicious app that looks entertaining and record whatever biometrics you're recording - Hand your phone to victim - Congrats, you have valid biometrics data (2d, depth information, fingerprint) you can use to login as a victim! Even better, they can't change their face or fingerprints You can invalidate old entries and detect variations but you still have a unsafer model. I can see a use for it if it's massively convenient (Eg. Detecting users in a physical location from CCTV) but if the user needs to take a selfie to login on a website, that could become annoying fast.
