Multi-Factor Authentication

Multi-factor authentication, or MFA, is a security mindset of using two factors to authenticate your identity when signing in to a website, application or other online services. These factors include something you know, like a username and password, and something you have, such as a smartphone or security key.

A common example of MFA is withdrawing money from an ATM. To gain access to your bank account, you need a bank card (something you have) and your PIN (something you know).

Duquesne University uses Duo to manage the second factor of MFA: something you have. Duo MFA allows you to authenticate into Duquesne online services, such as DORI and email, through a variety of ways, including:

  • Approving a Duo Push sent to your smartphone through the Duo Mobile app
  • Generating a one-time passcode with a Duo hardware token or in the Duo Mobile app
  • Answering a phone call to your mobile or landline phone
  • Tapping a YubiKey USB security key plugged into your computer.

You can choose which Duo authentication method you prefer each time you log in to Duquesne online services.


Why do I need to use MFA at Duquesne?

MFA helps protect personal information stored in your DORI and email accounts, such as grades, financial information, contact information and other sensitive data from malicious cyberattacks, such as phishing emails or password guessing.

While CTS has many tools in place to combat these attacks, students and employees can still be targeted. In almost all cases, MFA can help protect your personal information and sensitive data by adding an extra layer of security to your accounts.
