What is passwordless authentication?

Passwordless multi-factor authentication (MFA) uses PIN or biometrics together with any FIDO2-compliant authenticator such as hardware security keys (eg: Yubikey), Touch ID, Face ID, Windows Hello, or Android biometrics to log you in without typing in any username, password, or OTP.
