You can add administrators if you're a Partner Super Admin.
To add an administrator, do as follows:
Go to Settings & Policies > Manage Administrators.
Click Create Admin.
Enter the new administrator’s name and email address.
Select a role.
Select the customers they can access. You must choose at least one customer.
You can give the administrator the ability to select some customers or all customers. If you allow them access to all customers, this includes all your existing and future customers.
If you add a new Partner Super Admin, they have access to all your customers.
The administrator is sent an email with setup instructions.
