I want to protect my personal homepage by password. The homepage can be visited only if visitors input a correct password. I wonder how I can realize that in Dreamweaver?

Thank you in advance.

The easiest and quickest way is to use .htaccess - see http://www.javascriptkit.com/howto/htaccess3.shtml for an example

If your looking for a user login script, this one is very simple, easy to install and you can restrict access to pages to "members only"
