What is MFA
MFA stands for multi-factor authentication and basically means that you are using two different types of authentication to log into your account. There are three primary types of authentication factors:
Something only you know (e.g. password).
Something only you have (e.g. mobile phone w/ MFA app).
Something only you are (e.g. biometrics).
Why Should You Use It
Enabling MFA may be the single most important thing you can do to protect against cyber attacks.
