Remember when “security” means writing your password on a sticky note and hiding it under your keyboard? The good time now, when your face looks at your face, your phone is unlock, and your laptop salutes your finger like an old friend. Welcome to the biometric age – where your body is both key and locks, and will not forget your password until you forget your head.
So, what is actually happening when you use a facial recognition or fingerprint login? Devices like your iPhone Face ID Or Android’s Biometric prompt API Represent the mathematics of your unique features – not literally image or scan. Fingerprints, It is a map. For faces, this is a 3D depth model. That data is secretly stored and locally stored (usually in A Secure enclave chip), Mean also your highly curious tech overlords in Apple or Google may not browse your nose geometry by coincidence.
But is it in fact more secure? In most cases, yes – assuming that you do not have the same twin or 3D printer that has a bad series. Biometrics is difficult to estimate, it cannot be thwarted by email, and do not rely on your memory (a famous security risk). That said, they are not incompetent: researchers have fooled facial scanners with a hyper realistic mask, and once the biometric data leaks, you cannot “reset” your fingerprints at all.
