What Does Passwordless Authentication Mean?
Passwordless is an authentication scheme that uses possession factors (something the user has) and inherence factors (something the user is) instead of knowledge factors (something the user knows) to verify someone’s identity. Popular possession factors include smart phones and security tokens. Popular inherence factors include physical and behavioral biometric data from fingerprint scan matches or keystroke analysis.
Techopedia Explains Passwordless Authentication
Passwords have always been the weakest security link because weak passwords can be easy to guess, and strong passwords can be difficult to recall.
