LOL. If you have a decent enough spare Linux computer you can extract anything on a Windows system. Anything. Apple's is insecure in a different way through the user cloud connection. Itunes is a great hacking tool.This issue does not exist on windows
Essentially correct.I don't think so without restricting the user to a kiosk type desktop
Sensible answer is how about just using the lock screen when you walk away from your machine so others have no access... or you may be able, if you have the skill and time, to doctor up an android security cloud app to lock out the network configuration visibility to the user. I'm assuming (maybe but hard to tell) you don't want your kids to gain access to the WIFI password and then connect other devices. This can be accomplished by giving your computer a static address and blocking all other addresses in your router, so it won't matter if they have the password or not because your router will refuse the connection.
I guess you may be asking if there is a way to remove the view password check box from the NM UI. Probably yes but it would involve editing source code for several different parts of the system, UI, NM, Terminal, and other NM components, and in the end normal updates would probably restore it anyway because the default root functions could not be separated out. If the kid is not Linux savvy use NMTUI or NMCLI and don't install the graphical interface for NM.
