If you have access to an administrator account, you can sign in to the Google Admin console. The Admin console is where administrators manage Google services for people in an organization.

To sign in now (requires an administrator account):

In any web browser, go to admin.google.com. Starting from the sign-in page, enter an administrator account name and password. Forgot your password? An administrator account has privileges to manage services for other people in your organization. The Admin console is only available when you're signed in to an administrator account. If you don't have access to an administrator account, get help from someone else who does. Who is my administrator?

If you see a list of Google accounts on the sign-in page, be sure to choose an administrator account (it does not end in @gmail.com).

If your administrator account isn't listed, click the link to Sign in to a different account.
Tip: To switch between accounts on the same computer without signing in each time, see Sign in to multiple accounts.
