Multifactor Authentication

What is Multifactor Authentication (MFA)

Multifactor authentication (MFA) is a security process that requires users to provide two or more verification factors to gain access to a system, account, or application.

Instead of just entering a password (single-factor authentication), MFA adds extra layers of security by requiring additional factors, which typically fall into three categories:

• Something you know: This is usually a password or PIN.
  • Something you have: This could be a smartphone, security token, or smart card.
  • Something you are: This involves biometrics, such as a fingerprint, facial recognition, or voice recognition.
  • By combining multiple factors, MFA makes it much harder for unauthorised users to gain access, even if they have one of the factors, like your password.
