Multi-Factor Authentication (MFA)

What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication, also known as two-factor authentication or 2FA, is a security process that requires users to provide two or more forms of verification before gaining access to an account or system. This additional layer of security goes beyond just a username and password, making it much more difficult for cybercriminals to gain unauthorized access to accounts. There are three main factors that can be used in Multi-Factor Authentication: 1. Something you know – This is typically a password or PIN that only the user should know. 2. Something you have – This can be a physical device such as a smartphone, USB token, or smart card that generates a one-time code. 3. Something you are – This refers to biometric data such as fingerprints, facial recognition, or voice recognition. By requiring users to provide two or more of these factors, MFA significantly reduces the risk of unauthorized access, even if a password is compromised. This extra layer of security adds an additional barrier for cybercriminals to overcome, making it much more challenging for them to breach an account.
