Multi-factor authentication (MFA) is an increasingly popular approach that combines two or more verification factors, enhancing security by requiring additional proof of identity beyond traditional usernames and passwords.
These factors may include something the user knows (e.g., a password ), something the user has (e.g., a smartphone), or something the user is (e.g., a fingerprint or facial recognition). By incorporating multiple layers of verification, MFA fortifies the authentication process, making it more challenging for malicious actors to compromise accounts or sensitive information.
