Multi-Factor Authentication

Multi-factor authentication (MFA) adds an additional layer of security to protect your identity and university data. When you are only required to enter your username and password, this is considered single-factor authentication. MFA requires you to provide two of the following three types of credentials before gaining access to your account:

  1. Something you know (ex. an account password or banking PIN)
  2. Something you have (ex. a mobile phone or ATM card)
  3. Something you are (ex. a fingerprint or voice print).

MFA Withdrawal from ATM Example


Duquesne University uses Duo to manage the second step of the MFA process. With Duo, you can complete an MFA login process using any of the following methods:

  • Responding to a push notification sent to the Duo Mobile app on your mobile phone (CTS recommended method).
  • Entering a one-time passcode generated with the Duo Mobile app or a Duo hardware token.
  • Answering a phone call to a mobile or landline phone and following prompts to verify your login.

You can choose which Duo authentication method you prefer each time you log in.

You will be required to use Duo when logging into MFA-enabled applications and services. When signing in, you will only need to complete an MFA login process with Duo once every 12 hours.
