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:

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.

5. Remain on the Set up your account page while you set up and open the Microsoft Authenticator app on your mobile device.

7. Return to the Set up your account page on your computer, and then select Next.
The Scan the QR code page appears.

The authenticator app should successfully add your work or school account without requiring any additional information from you. However, if the QR code reader can’t read the code, you can select the Can’t scan the QR code link and manually enter the code and URL into the Microsoft Authenticator app.
9. Select Next on the Scan the QR code page on your computer.
A notification is sent to the Microsoft Authenticator app on your mobile device, to test your account.
