Setting up Microsoft Authenticator takes only a few steps, and once it's done, you won't need to do it again. You don't have to wait for a notice from ITC; you can set it up now and keep using Duo in the meantime. Once your account is migrated, you'll switch over to Microsoft Authenticator.

What You'll Need

• Your NetID and password.
• Your Duo-registered device and a computer to show the setup screen.
• The free Microsoft Authenticator app from the App Store or Google Play. A few apps have similar names, so double-check it's the one from Microsoft.

Step 1: Connect It to Your Dartmouth Account

1. On your computer, go to mysignins.microsoft.com/security-info and sign in with your NetID@dartmouth.edu.
   
2. Select Add sign-in method, then choose Microsoft Authenticator.
   
   Haven't installed Microsoft Authenticator yet? Click here to scan QR codes for easier installation.

   On your phone, install Microsoft Authenticator and open it.

   Scan the QR code below for the iOS version:

   

   Scan the QR code below for the Android version:

   

3. When prompted to install Microsoft Authenticator, hit the Next button.
   
4. You should get a notice to set up your account in the app. Hit the Next button to proceed. DO NOT enter a work or school email account.
   
5. A QR code will appear on your screen.
6. Open Authenticator on your phone and tap the plus icon (+), then choose Add account.
7. Select Work or School account, then tap Scan a QR Code.
   Note: If you have not allowed Microsoft Authenticator to use your device's camera, you will be prompted to give camera access to Microsoft Authenticator.
   If you can't use your camera to scan a QR code, click Can't scan the image on your PC and tap Enter code manually on your mobile.
8. After you scan the QR code shown on your laptop, Click Next, and then you'll see a two-digit number on your computer. When prompted, type that number into the Microsoft Authenticator pop-up on your phone.
   

Step 2: Confirm It's Connected

Once you've registered the app, your computer shows a screen confirming that Microsoft Authenticator was added successfully. Click Done.

If Something Isn't Working

• No prompt showing up? Open the app and pull down to refresh, and check that notifications are turned on for the app in your phone's settings.
• QR code won't scan? Make sure you're scanning from inside the app (the "+" Work or school account step), not your phone's camera.
• Stuck partway through? Close the app, reopen it, and restart Step 1.
• No smartphone? Toggle the "Get Help by School" option below to find your appropriate Help Desk or IT Group. 

Optional: A Few Recommended Settings

1. In the Microsoft Authenticator app, tap the menu icon (☰) in the corner of the screen.
2. Select Settings.
3. Under Security, turn App Lock off for a more convenient experience or leave it on if you'd like an extra layer of protection.

Once you transition from Duo to Microsoft Authenticator, your login experience will change. Here's what to expect:

What It Looks Like

1. Go to a Dartmouth app you sign in to - for example, Outlook - and enter your NetID@dartmouth.edu and Dartmouth password.
2. A two-digit number appears on your screen:

      3. Open the Microsoft Authenticator app and type that same number:

      4.  Tap Yes, and you're in!

Microsoft Authenticator doesn't move to a new phone on its own. Even if you use its cloud backup, your Dartmouth account won't carry over, for security, the credential is tied to your old phone and can't be copied or added to your account by anyone else. So when your phone changes, you set the app up again on the new one. Which steps you follow depends on whether you can still use your old phone.

If You Can Still Use Your Old Phone

This covers getting a new phone, or replacing one that still works (even a cracked-but-usable one).

1. Install Microsoft Authenticator on your new phone, see the "How to Enroll" section above for the download links.
2. On a computer, go to mysignins.microsoft.com/security-info and sign in as usual (approve the prompt on your old phone).
3. Select Add sign-in method → Authenticator app, and scan the QR code with your new phone.
4. Once the new phone works, remove the old phone from your list of sign-in methods.

If You Can't Use Your Old Phone (Lost, Stolen, Broken, or Gone)

When there's no way to approve a sign-in on your old phone, for any reason, the Service Desk gets you back in.

1. Contact the Service Desk (see "Need Help?"). They'll confirm it's you, remove the old device from your account, and issue a Temporary Access Pass, a short-lived code that lets you sign in once, with no device needed.
2. Sign in with the code, then set up your new phone by following the steps in the "How to Enroll" section above.
