Username / Password logins - HOW??
Depends what you're using. If you are using an Apache server, then you can implement it's standard permissions system. Here's a Google of tutorials: http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=apache+.htaccess+tutorial&btnG=Search
This is mainly useful if you have full control of your server. But even if you are hosted on an ISP, they normally make provisions for such requirements.
Additionally, you can set/change folder permissions on your web server, if you really want to do it simple.
Other than that, then you are getting into using heavier PHP/ASP etc. Which is not for the absolute beginner.
Username / Password logins - HOW??
All ISPs I've worked with allow using .htaccess files.
These look fairly easy to understand
