Using a Google Apps account
Many schools and businesses use Google Apps to manage their email, calendars, and documents. If your organization uses the latest version of Google Apps, you can sign in on your Chromebook with your organization's email address.
When you sign in, make sure you enter the password that is used for Google Apps. If you're not sure what password to use, contact your organization's network administrator.
Information for administrators
If you're the administrator for your organization, make sure your group is using the latest version of Google Apps by visiting your Google Apps control panel.
Visit the Enterprise Help Center for more information about single sign-on.
