Adding Additional Verification Methods for Multi-Factor Authentication

Last modified 4/19/2024

It is recommended that you set more than one verification method for Multi-Factor Authentication (MFA). This can be helpful if your initial method of verification is not available for any reason or experiencing any unforeseen technical difficulties. Setting an additional verification method will give you the option to Sign in Another Way when being asked to verify/authenticate your login to Microsoft 365 resources. The authenticator app method is the most secure and therefore, recommended as your primary method of multi-factor authentication.

Use the following steps for setting up an additional method of verification for MFA:

  1. Start by navigating to your MFA Account Portal at . If not already signed in, you may be asked to Authenticate/Verify your login.
  2. Click the + Add Method option (see Figure 1).

  3. If your initial choice when you first set up MFA was the Phone Call or Text option and you want to use the Authenticator Application, you will be asked to go through the set-up process for Adding the Application (see Figure 2). Detailed instructions for setting up the application can be found in the following knowledge article: Setting Up Multi-Factor Authentication using the Mobile App

  4. If your initial choice when you first set up MFA was the Authenticator Application and you would like to choose a phone call/text option, you will be called at the new number to verify it is you making the change. Make sure to have the new phone with you when making this change (see Figures 3 and 4). 

    Press the
    pound key (#) when prompted.

If you got a new device or are stuck in an authentication loop, you will not be able to add an additional method. This will require you to contact the Technology Support Center for a MFA reset.
