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 students, and mandatory for Faculty/Staff. If you would like to enroll in MFA, please contact email@example.com .

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 *insert App Password Article* to access your email.
