Question: 1 / 545

Which of the following is NOT a type of biometric authentication?

Fingerprint scanner

Facial recognition

Username password

Biometric authentication is a security process that relies on the unique biological characteristics of an individual to verify identity. This includes methods such as fingerprint scanners, facial recognition, and retina scanners, as they all utilize specific physical traits unique to a person.

Username and password combinations do not involve biological traits and instead rely on what a user knows. This method doesn't provide the same level of security as biometrics because it is more susceptible to being forgotten, stolen, or compromised through various attack methods such as phishing or brute force attacks. Therefore, the presence of usernames and passwords in the list highlights that this option is not aligned with biometric authentication methods.
