[Ask] Password protecting VNC Server (local)

[Heo Pv]

I'm using VNC Enterprise Edition and I don't know how to create a password to protect VNC Server Configuration. It mean that I install VNC Server on my computer which is a shared computer in my family. I don't want my parents, my brother have rights to control and edit VNC Server Configuration. My computer only have a shared account Administrator so I also don't want to create many accounts for management.

Would you please help me how to accomplish this? It's just a problems on local computer, not for remote computers.

Thanks for your help, best regards!
