Multi Factor Authentication

Multi-factor authentication (MFA) offers an additional layer of security to your emails and documents stored in the cloud on Microsoft 365. Below are the steps for setting up MFA once it has been turned on.

Step 1: Navigate to https://www.office.com/ and sign in to Microsoft 365 using the same coactive email address and password that you typically use to login to your email. 

After you click Sign In, you will receive the following prompt:

Step 2: Choose Next

Step 3: Select an authentication method:

Mobile app

  • Receive notifications for verification. This option pushes a notification to the authenticator app on your smartphone or tablet. View the notification and, if it is legitimate, select Authenticate in the app. Your work or school may require that you enter a PIN before you authenticate.

  • Use verification code. In this mode, the app generates a verification code that updates every 30 seconds. Enter the most current verification code in the sign-in screen.
    The Microsoft Authenticator app is available for Android and iOS.

 

Authentication phone

  • Phone call places an automated voice call to the phone number you provide. Answer the call and press the pound key (#) on the phone keypad to authenticate.

  • Text message ends a text message containing a verification code. Following the prompt in the text, either reply to the text message or enter the verification code provided into the sign-in interface.

 

Office phone

  • Places an automated voice call to the phone number you provide. Answer the call and press the pound key (#) on the phone keypad to authenticate.

Setting up MFA using the Microsoft Authenticator App

The default option for MFA that will be offered is to set up via the Microsoft Authenticator App. This is a free app that you would download on your phone. When you choose to use the app, you will open it whenever you are logging into Microsoft 365 apps and it prompts you to authenticate using MFA. The app will automatically generate a code for you to type in. This is a good option if you may not have reliable cell phone service, as it works over wifi. 

  1. You can download the Authenticator App on your mobile device using the following links:

  2. After downloading the authenticator App, open it and click on the + symbol in the upper-right corner.

  3. Choose Work or school account

  4. Select Scan QR Code

5. Scan (using your phone's camera in the authenticator app) the QR code that is displayed in a popup on your computer with your phone.

Setting Up Other Authentication Methods (Text/Phone Call)

If you would prefer to use a different authentication option, you can choose I want to setup a different method at the bottom of the prompt.

You will then have the option to setup multi-factor authentication using your mobile phone.

This means that you will receive a text message with a code each time you login to Microsoft 365 and need to authenticate. You will receive the 6-digit numerical code via text message and then enter it in the login prompt.
