Block Google Hangouts and Google Chat on school-managed Chromebooks

You can block all students in an organizational unit from using Google Hangouts and Google Chat on their school-managed Chromebooks.

Important: These steps work only on school-managed Chromebooks running Chrome OS.

Step 1: Block URLs

In the Google Admin console, click Devicesand thenChrome managementand thenUser & browser settings. Select an organizational unit, and next to URL blocking, enter these URLs:
  • https://hangouts.google.com
  • https://chat.google.com
Under URL blacklist exceptions, enter this URL:
  • https://hangouts.google.com/hangouts/_/meet
For more details about blocking URLs, go to Set Chrome policies for users or browsers: URL blocking.

Step 2: Whitelist only the apps your school needs

If your school uses Android apps on Chromebooks, we recommend whitelisting only the apps your school needs. To enable Google Hangouts or Google Chat for teachers in your organization, but keep those apps blocked for students, change the installation policy for student organizational units to Block.

For more information about whitelisting Android Apps, go to Deploy Android apps to managed users on Chromebooks

Note: To learn how to turn off Google Chat by organizational unit, go to Turn a service on or off for G Suite users.

Step 3: Set a sign-in restriction

To prevent students from using personal accounts to access blacklisted URLs in Incognito Mode, set a sign-in restriction on the school-managed devices for example.com.

For step-by-step instructions, go to Set Chrome device policies: Sign-in restriction.

For more information about Incognito mode, go to Set Chrome policies for users or browsers: Incognito mode.
