Multi-factor authentication (MFA) is a security method that requires two or more types of verification to confirm your identity to give you access.

 

Multi-factor authentication needs something you know (password, PIN), something you have (code from your phone, token, card) or something you are (fingerprint, or other biometric). 

MFA can prevent most of the common password-based cyberattacks that use stolen passwords from one site or account to break into other sites or accounts. 

MFA is not hard to set up and it can save you a lot of trouble in the future. It is a simple and effective way to protect your online security. 

Enable MFA to add security to your logins.
