If you're an administrator on a G Suite account, you can sign in to another user's account if you need to troubleshoot an issue or help with something. When you sign in as another user, that user's data isn't accessible to you. To sign in as another user:
Open your Google Admin console Sign in using your administrator account (it might have a different email address than your personal Google Account) Click Users. In the search box, type the name or email address of the user you want to sign in as. From the search results, click the user's name. On the right, click Impersonate . When prompted, enter your password again. You're now signed in to the other user's account.
As an administrator, you might also be able to delegate administration privileges to other users on your domain so they can manage specific aspects of your G Suite account. For example, you could delegate someone as a super administrator who has all administrative privileges for all services, or create a custom administrator role with more limited privileges for just a few services.
