Multifactor Authentication (MFA) - Changing Method from Phone (SMS) to App


Step-by-step instructions on how to switch MFA authentication methods from Phone (SMS or Voice) to Microsoft Authenticator App


Step 1. Download and install the Microsoft Authenticator app  

From your smartphone or tablet, visit the Apple app store or Google play store on your device and install the Microsoft Authenticator app. 

Note: Be sure that you are installing the correct free app, titled "Microsoft Authenticator"; there are several similar apps on the Apple App Store and Google Play Store.

Step 2. Access your preferred MFA options

From a computer, visit and login with your Dominican email address and password. You may be required to answer a verification request before you can proceed. After successfully signing in, you should see a webpage where the methods of MFA for your Dominican account can be configured:


Step 3. Add a new Method 

  • Below the words “Default sign-in method:”, you will select the option “Add sign-in method


  • After you click Add sign-in method, a window with a drop-down box will appear and you will select “Authenticator App” (1) and hit “Add” (2).



  • After selecting Add, you will be prompted to either download the Microsoft Authenticator app or use a 3rd party Authenticator app. Since you’ve already downloaded the Microsoft Authenticator app, click “Next”.



  • Then, on your phone or device, open the Microsoft Authenticator app. On the app, select the plus sign “+”.



  • Then, select the option to add a new “Work or school account” (1), followed by “Scan QR code” (2).

  • Using the Microsoft Authenticator app (1), scan the QR code on your computer screen (2).


 Step 3. Verify your device 

Once the account is added to the authenticator app, click “Next” on your computer. Your smartphone will receive a verification request and a set of numbers will appear on your computer. You will need to enter the numbers you see on the screen into the Authentication app. Once that is completed, you will receive a verification notification on your computer verifying approval.





Congratulations! Your mobile phone is now set up to receive push notifications for multifactor authentication verification.

From now on, you will only receive verification requests on your smartphone when attempting to access Microsoft 365 resources (email, OneDrive, etc.) or connect to the Dominican University VPN from off-campus.  
It is critical that you do not approve verification requests that you do not recognize.
