Office 365 multi-factor authentication set up

Modified on Wed, Apr 5, 2023 at 9:41 AM

In order to ensure that your account has enhanced security, your Office 365 and email accounts will be enabled for multi-factor authentication. Setting up this 2-step verification adds an extra layer of security to your Office 365 account. The 2-step process means that you will sign in with your password, and a code will be texted to your phone or you will have to approve the login with the Microsoft Authenticator app. First, however, you have to set up your account to use the 2-step process.

1. Sign into Office 365 with your work or school account with your password like you usually do.  

2. After you choose Sign In, you'll see the following page. Click on the Next button.

3. The window below will pop up. Here is where you choose how you want to have your accounts authenticated. Microsoft recommends that you use the Microsoft Authenticator app, and defaults to the app, but you also may choose to authenticate by text.  If you want to change to the text method, then press the I want to set up a different method link shown by the arrow in the picture below.

What's the difference? 

  • With the Microsoft Authenticator app you will just have to press either Deny or Approve in the app when prompted, and no text charges will apply. 
  • If you use the text-only method, you will receive a text and have to enter a 6-digit code on your login page.

Note: We do not recommend that you use your office phone for authentication because you would be restricted to logging into Office 365 while you are in your office only.
