Microsoft MFA - First time account setup


Every user will need to complete the initial setup steps to configure Microsoft Multi-Factor Authentication (MFA) for their Microsoft 365 account. MFA protects your account from threats such as phishing scams, malicious software, and malicious hackers by requiring a second form of verification along with your password. This MFA specifically applies to university Office365 accounts.


  1. The first step in configuring multi-factor authentication (MFA) is to visit Microsoft’s MFA setup page here:
  2. Once you have logged in, you will see the Additional Security Verification page. This page will allow you to set up the factors that will be used to verify your access when attempting to log in to your account.
  3. First, choose your preferred verification method- Information Technology recommends the setting "Text code to my authentication phone" option.

  4. Next, choose how you would like to respond. Information Technology recommends that you set at least two options, such as an authentication phone (to receive SMS text codes) and the optional Authenticator app.
