If you want to keep some content hidden from the public eye, you'll be able to activate password protection for a given folder - either the main site folder or a different one below it. In case this option is turned on, a pop-up will appear each and every time somebody attempts to open the folder in question or clicks on a direct link which goes a few levels deeper, so login information shall be needed for www.domain.com/folder/image.jpg when you have protected the domain.com folder. In case the credentials are not valid, a “403 Forbidden” message will appear and there's no way of getting around this restriction, so you can rest assured that no one will be able to access the protected content. The function can be helpful in a variety of scenarios - if only a number of people should be able to see particular files, if you work on an Internet site and you do not want people to see it before it is completed, and so on.
