If your account needs to have enhanced security, the Enterprise Applications and Servers department will enable your account to have 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 Set it up now button.
3. The window below will pop up. Here is where you enter your cell phone information and choose how you want to have your accounts authenticated - you will need to enter the cell phone number in either case. Microsoft recommends that you use the Microsoft Authenticator app, but you also may choose to authenticate by text. 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 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.
