The following steps will walk you through the process of setting up the Microsoft Authenticator App on your phone to generate a verification code used for Multi-Factor Authentication (MFA).
To start, click on the following link: https://aka.ms/MFASetup. You will need to sign in if you haven’t already. It will take you to the “Additional security page” below:
Under “what’s your preferred option?” select from the drop down menu “Use verification code from app or token”:
Under "how would you like to respond?" select "Authenticator app or Token" then click "Set up Authenticator app":
The "Configure mobile app" screen will appear. (Leave this window up as you install the Microsoft Authenticator app):
For step 1, click on the correct type of phone you have; Windows Phone, Android, or iOS:
This will open a new link to the appropriate place to download Microsoft Authenticator for your phone type. Install the correct version of Microsoft Authenticator for your phone:
Once the app is installed, add an account, and select "Work or School Account".
Select scan QR code, then return to the "Configure mobile app" screen on your computer and scan the QR code with your phone. (You may need to change settings to allow Microsoft Authenticator to access the camera in settings):
(QR code example. Scan the QR code on your "Configure mobile app" screen. QR code will not have red dot)
You will be prompted to enter the current one-time password code on your Microsoft Authenticator app. (This code is automatically generated every 30 seconds in the app):
Once you have entered the code, click "Verify" to complete your set up.
You are now set up to use a verification code from the Microsoft Authenticator app. When you are signing into your account and are prompted to authenticate, you will enter the current one-time password code given in Microsoft Authenticator to approve the sign in. This is same process as you did in the last step above to verify the app.
