Always rename your admin account to something difficult to guess. Name it, theJoomlaGod, damina, joesixpack, or anything you want to, but do change it to something other than admin. This is one of the most effective things you can do to protect and secure your Joomla installation.
Why you should rename you Joomla admin account
Our websites did get their password reset, however they were not defaced. This is because the first thing we do after we install Joomla, is rename the admin user to something more sensible, and something difficult to guess. This ensures that most kinds of hacks which target the admin user do not work.
It also makes sure that anybody who tries to use common passwords or brute force attacks against your administrator password will not succeed.
