Google MFA: Multi-Factor Authentication Using A Mobile Device

Modified on: Tue, Mar 11 2025 9:05 AM

Use this process to set up Multi-Factor Authentication (a.k.a. MFA / 2-Step Verification) for your Google account using your mobile device.  When using a mobile device for Google MFA, it is required to have two methods set up:  Google prompts as your primary method and Google Authenticator as your secondary.  Follow the steps below to set up both methods.



Do you want to use a Security Key (a usb device that plugs into the USB port on your district-provided computer) for 2-Step Verification? Non-administrative GBSD employees can request a district-provided Security Key from the Service Desk.


Set Up Google Prompts

On your mobile device

  1. Make sure you’re signed in to your Google Account on an Android phone or iPhone.
    1. If you have an iPhone:
      1. Turn Bluetooth on.
      2. Get the Google Smart Lock app from the App Store.
      3. Sign in with your district provided Google account.
    2. If you have an Android phone:
      1. Open the Settings app on your phone.
      2. Tap Accounts, then Add Account.
      3. Select Google and sign in.

On your district provided computer

  1. Log into your email.
  2. Click the Enroll button when you see the 2-Step Verification warning (or, go directly to the Google 2-Step Verification set up).

    Note: If you do not see a device listed, click on the Don’t see your device? link and follow the instructions provided.

  4. Next, Google will prompt you to save backup codes.
    1. Backup codes are not necessary for district provided accounts. If you choose to save them, ensure that they are kept in a secure location.
      Note: Backup codes are very important for personal accounts. If you set up 2-Step Verification on a personal Google account please save the information somewhere secure.
    2. If you choose not to save them, skip this step by clicking on Next at the bottom of the page, then click I have my codes in the pop-up window.

  5. Review the 2-Step Verification information and then select Turn On.
    Turn on 2-Step Verification
  6. Set up is almost complete!  Please go to the next section to set up Google Authenticator.
