Office 365 Multi-Factor Authentication

Multi-Factor Authentication (MFA) is a secure authentication method that prevents malicious access to an account by using multiple methods of authentication combined. For Office 365, this is most commonly using your email/password and your phone. Once you have been enrolled in MFA, you will have multiple methods available to you. However, our guide provides the most time efficient method of MFA. For this process, you will need your smart phone and your computer handy, since you will be switching between the two.

IF YOU HAVE YOUR EMAIL ON YOUR PHONE, YOU MUST REMOVE THE ACCOUNT FROM YOUR PHONE FIRST. When you add the account back onto your phone after setting up MFA, it will work correctly.

MFA enrollment is opt-in for most users. If you would like to enroll in MFA, please contact .

5. Lastly, you will be introduced to your App Password. This is a unique password that you can use for logging into your account on devices that do not support MFA. Your app password is generated automatically by the system and CAN ONLY BE VIEWED ONCE. You can create additional App Passwords if necessary through the Office 365 portal.

That's all there is to it! Whenever you sign in to Outlook or the Office 365 portal, you will be prompted to approve the Sign-in. In addition, you will only have to approve a sign-in on your Outlook program once every 14 days. If you have any questions, please contact us at .


Q: Why doesn't the Email app on my Android work with MFA?

A: You must use the Outlook app for Android if your account has MFA enabled.

Q: It doesn't let me choose my office phone as an option. What should I do?

A: Please choose the option "Authentication Phone" instead. Then you can put in your office number.

Q: My phone's email app isn't accepting my password after setting up MFA. What am I doing wrong?

A: When you originally setup your account on your phone, it was configured to not be a MFA account. If you delete your account off of your phone and re-add it, it should resolve this issue. Or you can use an App Password to access your email.

Q: How do I change my verification method for MFA?

A: You can change your verification method inside of the Office 365 Web Portal. While we outlined the steps to configure the app, all verification methods are acceptable. Here are the steps:
