Web-page protection is used to limit access to any directory to users who enter a username/password combination. To protect a directory within your account:
1.) Click on that directory;
2.) Enter a username / password to gain access;
3.) Click add.
You can add as many users as you wish to this file. This protection is for resources accessed via the Internet only, and this will not create an FTP user.
However, do not use this system if you are already using a different login system, as the two are not necessarily compatible.
