Set up your Microsoft 365 sign-in for multi-factor authentication (MFA)

Content

    1. 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.

      A dialog box telling you that more information is required to complete your sign-in

    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.

      If you would rather use SMS messages sent to your phone instead, select I want to set up a different method. Microsoft 365 will ask for your mobile number, then send you an SMS message containing a 6-digit code to verify your device.

      Tip:
      For a faster, and more secure, experience we recommend using an authenticator app rather than SMS verification.

      1. The Configure mobile app page appears.

      2. Open the Microsoft Authenticator app, select Add account from the Customize and control icon in the upper-right, and then select Work or school account.

        Note: If you receive a prompt asking whether to allow the app to access your camera (iOS) or to allow the app to take pictures and record video (Android). select Allow so the authenticator app can access your camera to take a picture of the QR code in the next step. If you don't allow the camera, you can still set up the authenticator app as described in Manually add an account to the app.

      3. Use your device's camera to scan the QR code from the Configure mobile app screen on your computer, and then choose Next.

       

    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.

      Note:
      You'll only need the additional verification method the first time you sign into a new app or device, or after you've changed your password. You'll be asked for an additional verification code every two weeks.
