Insert password protected folders into Dreamweaver

I'm currently re-designing my website. Have managed everything except an added page for which it will hold password protected folders for clients to view. This is something I've never done before or know how. The page is already set up, with the folders (currently have 3 folders) and have the text for where the 'password protected text' needs to go. I imagine I'd need to dropbox my new website as it's not up yet. Thanks for your time
