Question

How do I setup the Authenticator app for MFA? 

Answer

We strongly recommend setting up more than one verification method. It is the easiest verification method to use, and a way to avoid text or call charges.

  1. Open a browser on your computer and go to portal.office.com. Sign in to your Office 365 for business account.

  1. Wait for configuration pop-up box; you should see a window on your computer that looks like this.

  1. Add account to Microsoft Authenticator
  • Open the Microsoft Authenticator app on your phone.
  • Tap the + > Work or school account.

  • Use your phone to scan the QR square that is on your computer screen.
    • iPhone users may have to enable the camera in Settings in order to scan.
    • If you cannot use your phone camera, you will need to manually enter the 9-digit code and the URL.
  • Your account will be added automatically to the app and will display a six-digit code.
  1. Confirm activation status on your computer
  • Switch back to your computer and click Done.
  • Now wait for the Checking activation status text to finish configuring your phone.
  • When it is complete, you will be able to click the Contact me button on the right.
    • If configuration fails, delete and retry the previous steps again.

  1. Approve sign in on your phone
  • Switch back to your phone and you will see a notification for a new sign in.
  • Go to the Microsoft Authenticator app.

Tap Approve to allow it

  1. Finish set up
  • Once back on the computer, follow any prompts that you might see such as adding a mobile number.
  • You are good to go!

From now on, whenever you have a new sign in or add your Office 365 work or school account to an app, you'll open the Authenticator app on your phone and tap Approve.
