Control Center-Configure servers-Manage URL access users

In order to restrict access to certain parts of your website your can create password protected directories. First, you should create password protected area, so called realm. Then you have to assign directories that you want to be protected to this realm and finally you have to add users that can access directories assigned to the realm. Realms are managed at "Manage protected URL" and users are managed at "Manage URL access users".

If you want to have another protected area with different access users you have to create another realm and add different users to it.
