What Type of Authentication Combines a Password and Fingerprint Scan? Multi-Factor Authentication for CCST Cybersecurity
Table of Contents
Question
A cybersecurity team is implementing a policy that requires users to verify their identity using a fingerprint scan along with a password. What type of authentication is this?
A. Single-factor authentication
B. Multi-factor authentication
C. Multi-factor authentication
D. One-time password authentication
E. Identity federation
Answer
B. Multi-factor authentication
Explanation
Multi-factor authentication (MFA) uses multiple authentication methods (something you know and something you have or are) to improve security.
Requiring users to verify their identity with both a password and a fingerprint scan is an example of multi-factor authentication (MFA).
Multi-factor authentication (MFA) is a security process that requires users to present two or more independent credentials from different categories to verify their identity.
The three primary authentication factor categories are:
- Something you know: e.g., password or PIN.
- Something you have: e.g., security token or smart card.
- Something you are: e.g., biometric data like a fingerprint or facial recognition.
By combining a password (something you know) with a fingerprint scan (something you are), MFA significantly increases security. Even if one factor is compromised, unauthorized access is prevented unless the attacker also possesses the second factor.
MFA is widely recommended and often required in regulated industries to protect sensitive systems and data from unauthorized access.
MFA uses multiple authentication methods, such as a password and a fingerprint scan, to provide stronger security than single-factor authentication.
