A password-protected directory or area is a folder that may be accessed only when a username and a password are typed in, so no unauthorized people could look at its content. This function may be used for the main folder of a specific website or just for a specific subfolder in accordance with your needs. For instance, when you are building a new website and you do not want people to see it prior to it being 100% ready, you might want to limit the access to it completely, while if you want only some people to be able to access particular files, you are able to password-protect only a certain folder, while the rest of the site could be seen by anyone. In any case, a “403 Forbidden” error page shall appear in the event that the login details the visitor enters aren't right. Even a direct link to a file won't work so long as any folder above it is password-protected.
