How to Setup and Edit Office 365 Multi-Factor Authentication (MFA)


This guide will assist in setting up an account with Office 365 Multi-Factor Authentication (MFA).  MFA will require you to complete additional authentication when signing into Office 365 resources (this includes web and desktop versions of Outlook, Skype for Business, OneDrive, and more). Where most typical authentication procedures require a username and password only, multi-factor authentication will require you to authenticate your identity using an additional method.

Office 365 MFA Verification Methods

Microsoft has a set of defined methods you will select in the setup process to provide the additional verification when accessing Office 365 resources:

  • Text message sent to your phone with a code to enter into the verification screen
  • Phone call attempting to authenticate 
  • Mobile app to deny or approve

Once your multi-factor authentication is setup, you will be required to approve any new requests to access your Office 365 account. Some instances of when you will be required to approve MFA requests include:

  • Signing into Outlook, OneDrive, Skype for Business, or another Office 365 application after shutting off your computer,
  • Signing into an Office 365 application on a new device.

Steps to Set up Multi-Factor Authentication Verification Methods

Most accounts are automatically required to use Multi-Factor Authentication and you will be prompted to configure your authentication methods the first time you sign-in to Office 365.
