Biometric authentication is a form of multifactor authentication (MFA) that verifies a user’s identity based on their unique biological characteristics [00:00:15].
It serves as a second method to confirm that the person accessing an account is who they claim to be, in addition to a password [00:00:05].
A very common example of biometric authentication used as a means of MFA is Face ID [00:00:15].
