Multi-Factor Authentication

MFA, sometimes referred to as two-factor authentication or 2FA, is a security enhancement that allows you to present two pieces of evidence – your credentials – when logging in to an account. Your credentials fall into any of these three categories: something you know (like a password or PIN), something you have (like a smart card), or something you are (like your fingerprint). Your credentials must come from two different categories to enhance security – so entering two different passwords would not be considered multi-factor. You probably already use MFA, some example include:

  • Swiping your bank card at the ATM and then entering your PIN (personal ID number).

  • Logging into a website that sent a numeric code to your phone, which you then entered to gain access to your account.

MFA helps protect you by adding an additional layer of security, making it harder for bad guys to log in as if they were you. Your information is safer because thieves would need to steal both your password and your phone..

When should I use MFA? Whenever possible, especially when it comes to your most sensitive data.
