Configuration - System - Users

Begin configuration mode and select ‘System – Users’ to gain access to the button ‘Add Admin’. This allows you to enter a username with a password and an e-mail address. The e-mail address is used for the ‘Forgot password’ option on the login screen. A new password can then be created and sent to the user’s e-mail address.

When you add an administrator in the back-end, a ‘User parent’ must be specified. This is an existing user in charge of the new user, which in practice is often a previously established administrator.
