A password-protected directory or area is a folder which may be accessed only when a username and a password are typed in, so no unauthorized people could view its content. This option could be used for the main folder of a specific Internet site or only for a specific subfolder in accordance with the needs you have. As an example, when you are creating a new Internet site and you don't want people to see it prior to it being completely ready, you might want to restrict the access to it as a whole, whereas if you would like only some people to be able to access certain files, you could password-protect only a particular folder, while the remainder of the Internet site may be seen by anyone. Regardless, a “403 Forbidden” error page will appear if the login details the visitor types in aren't accurate. Even a direct link to a file shall not work so long as any folder above it is password-protected.
