Multi-factor authentication (MFA) is a security process that requires individuals to provide multiple forms of identification before granting access to a system, application, or digital account.
The goal is to add an extra layer of security beyond just a username and password. MFA is designed to enhance the protection of sensitive information and reduce the risk of unauthorized access.
The three main factors used in multi-factor authentication are typically:
Something You Know: This is typically a password or a PIN (Personal Identification Number). It's information that the user is expected to know.
Something You Have: This involves a physical device or token that the user possesses, such as a smartphone, security token, or smart card.
Something You Are: This refers to biometric data, such as fingerprints, retina scans, voice recognition, or facial recognition.
