Description:

Two-Factor Authentication (2FA) works by adding an additional layer of security to your online accounts. It requires an additional login credential – beyond just the username and password – to gain account access, and getting that second credential requires access to something that belongs to you.

By setting up MFA, you add an extra layer of security to your Microsoft 365 account sign-in. For example, you first enter your password and, when prompted, you also type a dynamically generated verification code provided by an authenticator app or sent to your phone.

The Microsoft Authenticator app helps you sign in to your accounts when you're using two-factor verification. This app is available for download in your Apple App Store & the Google Play store. 

You WILL need this app to access your Office 365 account.

Follow the steps below to setup Office 365 2-Factor Authentication:

• Sign in to Microsoft 365 with your work or school account with your password like you normally do. After you choose Sign in, you'll be prompted for more information.
• Choose Next.
