How to setup MFA (Multi Factor Authentication) and the Microsoft Authenticator App on your MS 365 Account
Once your administrator has enabled MFA on your account, the easiest way to login is by using the Microsoft Authenticator app. By setting up MFA, you add an extra layer of security to your Microsoft 365 account sign-in. For example, you first specify your password and, when prompted, you also type a dynamically generated verification code provided by an authenticator app or allow the sign in via a prompt on your phone.
First download the app for your device from the link below:


1. Sign into Microsoft 365 with your work or school account with your password like you normally do. If this if the first time you have signed in, you’ll be prompted for more information.
2. Choose Next.

3. The default authentication method is to use the free Microsoft Authenticator app. If you have it installed on your mobile device, select Next and follow the prompts to add this account. If you don’t have it installed there is a link provided to download it.

4. Once you complete the instructions to specify your additional verification method, the next time you sign in to Microsoft 365, you’ll be prompted to provide the additional verification information or action, such as typing the verification code provided by your authenticator app or sent to you by text message.
