Multi-factor authentication (MFA) has become widely implemented throughout many different types of websites and applications across the world. But what exactly is MFA, and why is it necessary?


MFA is an authentication method that requires you to provide two or more verification factors to gain access to a resource, such as an application or an online account. MFA combines two or more of the following credentials to verify your identity:

  • Something you know (password, pass phrase, pin)
  • Something you have (security token, landline, second computing device)
  • Something you are (biometrics, like fingerprint and face ID)

Duo is the University's MFA software, and is required for all University faculty, staff, and students. Duo creates a layered defense against unauthorized access to your accounts. If an unauthorized person obtains your password, they will not be able to log into your account because they would also need access to your device, e.g., your cell phone, landline, tablet, or token that is enrolled in Duo.

Whether it's a University resource or a personal account, MFA should be enabled whenever possible!
