Enroll Your Device

 Please Note:
 Starting Monday, October 30, 2023, you will be required to enter a six-digit numeric code with any Duo push notification.

Duo Two-Factor Authentication (2FA) adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile devices) helps prevent anyone but you from logging in—even if they know your password.

Duo 2FA will be used to verify your identity when logging into certain SMU sites, and can help prevent unauthorized use of your SMU account. Download the Duo Mobile app from your smartphone's app store using the links below:



Get Started

  1. Download the Duo Mobile app from your smartphone's app store.
  2. Use your desktop or laptop computer, click the "Enroll Your Device" button above.
  3. Follow the on-screen Duo enrollment instructions. We suggest having your smartphone available to scan a QR code with the Duo Mobile app.

Please Note: These instructions are for new users only. For those re-enrolling a device, please call the IT Help Desk at 214.768.HELP (4357).

 For any issues involving Duo two-factor authentication (2FA), including forgetting your phone or setting up a new device, you will need to contact the IT Help Desk directly at 214-768-HELP (4357). Assistance via chat or email is not available for Duo.
