Biometrics is a fruit of practical research studies in STEM—science, Technology, Engineering, and Mathematics.  * The practical research in biometrics revealed that biometrics-based recognition is probabilistic, NOT deterministic. * But [biometrics has inherent and intrinsic problems](https://read.cash/@Unity/biometrics-got-intrinsic-problems-11abdcb9) that can't be surmounted externally. > Then, how could a probabilistic process of biometrics recognition be used to yield a deterministic "yes/no" result? * No external technology agents or processes can make biometrics-based authentication as deterministic to yield a deterministic "yes/no" result like text passwords/PINs. * Additionally, several other problems and vulnerabilities exist in biometrics-based recognition, including biometrics spoofing, false acceptance, false rejection, and 'credential stuffing.' * Moreover, biometrics can be collected and copied from public places and social media spaces, and biometrics can't be reset like text passwords/PINs. * That is why biometrics is inherently unreliable. * Hence, biometrics is not fit for authentication use cases.
