A password-protected directory or area is a folder that may be accessed only if a username and a password are entered, so no unauthorized people may view its content. This feature could be used for the main folder of a specific Internet site or exclusively for a certain subfolder depending on your requirements. For example, if you are creating a new Internet site and you do not want people to see it before it is ready, you might want to restrict the access to it as a whole, whereas if you need only some individuals to be able to access particular files, you'll be able to password-protect only a particular folder, while the remainder of the website could be seen by everyone. Regardless, a “403 Forbidden” error page will appear when the login details the visitor enters aren't right. Even a direct link to a file won't work provided any folder above it is password-protected.
