Storing your login and password name may be convenient, but it is not secure. The password is available to anyone who uses the server machine.
Changing the administrator password and port is a good option if you do encounter a security breach.
Note: It is so easy to configure the server that many administrators do not give careful consideration to administrative password or port changes. If you can not remember your password and port, you can not connect to the server.
Carefully consider inheritance as you begin to grant folder access to different VFS groups. Creating virtual folders gives users access to all subfolders of the folder you point towards.
Setting VFS access with patterns of inheritance derived from parent folders in a logical manner ensures that permission groups have predictable access to folders.
