2 Factor authentication is an extra layer of security that requires, in addition to your regular username and password, a separate piece of information that only you can access.  This can be a code received on your mobile device or a unique piece of hardware.  This limits the effectiveness of simple password hacks and social engineering exploits.

Enabling 2 Factor Authentication

Before you begin, you'll need to decide how you'd like to receive your two-factor code.  Your options are as follows:

  1. Use the Google App on your Clarkson smartphone, personal smartphone or tablet (install from your App Store before proceeding)
  2. Text message on your Clarkson cell phone or personal cell phone
  3. Voice call on land-line phone
  4. USB-based hardware key (department funded - please contact the HelpDesk for additional information)

With your choice made, now you can proceed with the steps below.

  • Navigate to Google's main 2 Factor authentication page ( and Click on the "Get Started" Button.
  • If prompted, log into the account you wish to protect with 2 factor authentication.  Otherwise, click on the "Sign In" button and follow the prompts to sign into your account.  In some instances, you may have to do both.

  • Once logged in, you will be taken to Step 2.  Turn On 2-Step Verification.


  • Select the device of choice.  If you select text, enter the number Google should text to.  Click Next.

  • Enter code that Google sends.  

    • If you choose NOT to use a mobile device, you will not be able to use text message verification in this or later steps of this guide.
    • If you choose to use a LANDLINE, that is the only device you will be able to use to authenticate you account in the future.

  • Depending on your choices above, you will receive a verification code as a text or voicemail.  Enter that code into the box labeled "Enter the code", on the page that opens. (Fig 2)
  • On the new page that opens, click "Turn On". (Fig 2)

  • 2 Factor Authentication is now enabled on your account with the default settings enabled and you will begin receiving codes through voice or text messages when you are required to authenticate your login.

Creating Backup Codes

In the event that Google asks you to authenticate your login and you do not have access to your choosen authentication method, you will need backup codes.  Please follow these steps to print out your unique backup codes.

  • Login to your Clarkson Google account and navigate to the "Sign-in & Security" page:
  • On the left hand navigation pane, click on "Signing Into Google".  This will take you to the "Signing Into Google" section of the webpage. (Fig 3)
  • Click on the arrow next to your enabled "2-Step Verification" section.  (Fig 3)

  • On the "2-Step Verification" page that open, click on "Setup" in the "Backup Codes" section.  (Fig 4)
  • On the page that opens, click on "Print" to obtain your codes to store in a safe place. (Please note, this document contains sample codes only.)  (Fig 4)

Using the Google Authenticator App

Install the App

  • Visit the Apple App store or Google Play
  • Search for Google Authenticator
  • Download and install the application

Setup the App

  • On your computer, go to the 2-Step Verification settings page and click on Android or iPhone
  • On your mobile device, open the Google Authenticator application.
  • If this is the first time you have used Authenticator, select Begin setup. If you are adding a new account, choose Set up account from the app's menu.
  • To link your mobile device to your account:
    • Using QR code: Select Scan a barcode. If the Authenticator app cannot locate a barcode scanner app on your mobile device, you might be prompted to download and install one. If you want to install a barcode scanner app so you can complete the setup process, select Install, then go through the installation process. Once the app is installed, reopen Google Authenticator, then point your camera at the QR code on your computer screen.
    • Using secret key: Select Enter provided key, then enter the email address of your Google Account in the "Enter account name" box. Next, enter the secret key on your computer screen in the "Enter your key" box. Make sure you've chosen to make the key Time based, then select Add.
  • To test that the application is working, enter the verification code on your mobile device into the box on your computer next to Code, then click "Verify."
  • If your code is correct, you will see a confirmation message. Click "Save" to continue the setup process. 

Authentication for External Applications

In some cases, after setting up two-factor authentication for your Google account, you may have trouble logging into programs that use Google for authentication.  If this occurs, one thing to try is setting up an "Application Password" for that app.  Please follow Google's documentation for doing this, located here:
