-You will only be asked to set up your password the first time you run ''paraview-vnc''. Make sure to remember that password as you will need to use it to login into your VNC sessions for ParaView in the future. If you don't get prompted for a password and you don't remember what you entered before, then you will need to clean up your account before running ''paraview-vnc'' again.
+You will only be asked to set up your password the first time you run ''paraview-vnc''. This should **NOT** be your login password! This mechanism only deters unauthorized connections; it is not fully secure, as only the first eight characters of the password are saved. Make sure to remember that password as you will need to use it to login into your VNC sessions for ParaView in the future. If you forget your password then you can use the ''vncpasswd'' command to reset your password.

 The base port for VNC is 5900, add your display number '':1'' (that can be found in the above code segment) and we get 5901.
