Administrator privileges give a user rights to manage other user's access to Google Apps or to perform actions that affect the setup of your organization's Google Apps account. Please note, creating more than three super administrators for your domain can inhibit some administrator account recovery options. See Reset the administrator password for an explanation of that process.
You grant a user administrative privileges by assigning one of the available administrator roles to the user. The Admin console offers pre-defined administrator roles for common business scenarios, or you can create custom administrator roles for different combinations of privileges.
You can make a user either a Super Administrator with complete access to the Google Admin console, or you can assign a role that limits which administrative tasks the user can perform. For example, the User Management Admin role grants a user rights to manage user access to Google Apps (create new user accounts, reset passwords, and so on), but not update domain settings or perform any other administrator action.
At least one user in a domain needs to be a super administrator, and only a super administrator can assign administrator roles to other users. To change your super administrator account, assign the super administrator role to a second user account, then sign in with the second user account to remove the super administrator role from the initial account.
