Multifactor Authentication (MFA) Initial Setup with an Authentication App

MFA can be configured via Text Message, an Authentication App, or both.

To use an app, download from the app store for your device.

Time needed: 10 minutes

Multifactor authentication (MFA), also known as two-factor authentication (2FA), is a feature which allows users to better protect their account by requiring additional steps when signing in. MFA increases security on your account by requiring you to first sign in using your username and password, then approve the sign in request using a second factor like your mobile phone.
We recommend installing the Microsoft Authenticator to your mobile phone. It is available on both the App Store for iPhone and Google Play for Android. You can easily Approve or Deny login requests via a prompt on your phone.
