Manage apps and extensions

This article is for Chrome for Work and Education administrators.
Chrome web app pack

Chrome application settings in the Admin console allow administrators to control which Chrome applications and extensions users can access, and whether users can create and publish their own apps. To manage application settings:

  1. Sign in to the Admin console.
  2. Click Manage devices > Chrome Management > User settings.

From the User settings page, you can do the following:

  • Set Pre-installed Apps and Extensions
  • Specify Allowed Apps and Extensions
  • Set the Chrome Web Store Homepage to a custom homepage for your users.
  • Allow users to publish private apps that are restricted to your domain on the Chrome Web Store.

Note that these last two Chrome Web Store settings only work for organizational units that have the Chrome Web Store setting enabled under Organization & users > Services.

By default, users can install any extension or application. As administrator, you can block specific apps and extensions, or block all apps and extensions except for specific ones that you approve. You can also pre-install specific apps and extensions. Your users won't be able to uninstall any items added to the pre-install list.

  • To block specific apps and extensions, select Allow all apps and extensions except the ones I choose (the default selection), click the Manage link that appears below the radio buttons, then choose the items to block as described below.
  • To block most extensions and applications, select the option Block all apps and extensions except the ones I choose, click the Manage link that appears below the radio buttons, then choose the items to allow as described below.
  • To pre-install specific extensions and applications, click Manage pre-installed apps and choose the items to pre-install as described below.
Notes about preinstalling apps and extensions:
  • To select extensions, you must have the Chrome Web Store service enabled for your organization.
  • Apps and extensions added to the pre-install list will bypass the list of blocked apps and extensions. In other words, Chrome apps force installed via the Admin console, Google Play for Education, or Chrome GPO ExtensionInstallForceList take precedence over apps you've blacklisted.

You identify the specific extensions or applications to block, allow, or pre-install using the Chrome Web Apps & Extensions dialog box that appears when you click one of the Manage links. The text below the title indicates whether you are selecting Blocked apps and extensions, Allowed apps and extensions, or Pre-installed extensions.
