A description of multi-factor authentication
What is MFA?
Multi-factor authentication (MFA) strengthens access security by requiring multiple methods (also referred to as factors) to verify your identity. These factors can include something you know - like a username and password, plus something you have - like a smartphone app to approve authentication requests. MFA helps protect against phishing, social engineering and password brute-force attacks and secures your logins from attackers exploiting weak or stolen credentials.
