first thing- check your hosting.
If you have a control panel or CPanel, there are icons in there to password
protect a directory and add authorized users. Put that page inside the
protected directory.

It's an Apache server, can you use php scripting on it?
If yes- this free script will put an admin page in whatever folder you drop
it into, which will allow you to add/edit/delete authorized users.
It takes care of making the htaccess and pswrd files.
