Max's Site Protector
Max's Site Protector is a simple PHP based script which helps you to protect your pages with password. Setting up a password protected page is very easy. You only need to add 1 line of code to all of your pages you want to protect and that's all. You need to login only once and all protected pages will be available for you. The script uses CSS so changing the style is very simple. An example code is attached to the installation package.
