How to change freepbx/fpbx to something else

I have read most of the forums. I can not find a simple way to change the freepbx/fpbx to something else. I made all the changes to the admim user in manager.conf and amportal.conf but these changes do not apply to the freepbx user I enter to login to the web management page. After I made the changes I can still login the default username/password known by almost everyone in the community. Does anyone know how to do this?
I would appreciate any help because I have been reading for almost a week and all forums point back to changing the secret =amp111 (already changed)but had no impact on login it the the management web page.
Thank you
