How to Add Biometric Passwordless Authentication to Any Web App

Passwordless authentication refers to verifying a user’s identity without an actual password. Such a way of authentication contributes to higher security because it uses biometrics – which refers to physical traits of the user such as fingerprint, and possession factors like one-time-passwords delivered to smartphones or other devices.
