How to Setup the Microsoft Authenticator App for MFA

How to Setup or Update Multi-Factor Authentication (MFA)

What is MFA?

Multi-Factor Authentication (MFA) is used to make sure you are who they say you are by requiring two or more factors [pieces of evidence] that prove your identity. The requirement of a second factor greatly increases the security of your account, as just knowing or guess your password is not enough to access your account. These factors are a combination of:

  • Something you know, such as a password or passphrase

  • Something you have, such as a code from a smart phone app or security token

  • Something unique to you, such as a fingerprint or retinal pattern

With MFA enabled, you will be prompted for a second factor after entering your username and password when logging into a supported service such as Microsoft Outlook, Teams, etc.
