There are lots of ways to make sites password protected some dependent on your host's operating system.
Rather than try to teach it here in a post, I would recommend you look through certain websites with detailed instructions.
One of the most popular methods on UNIX platforms is the htaccess file method, in which the htaccess file references a list of acceptable users and passwords before letting someone see the file.
There will be lots of help forthcoming.

Take a look at the below post, and in particular msg#3, which explains how to implement and use htaccess.
