How to bind the program to the computer?

Question

JavaScript

I am making an application for windows. I am writing a client on electron + angular. I need to bind the program to the computer so that I can see the key in angular. In my idea, I have to check this key with the one saved on the server, because it must be static. The MAC address does not match. In my other implementation, I found that it changes when switching Wifi and Ethernet

Answer 1

Before spoiling the lives of loyal users with hardware bindings (which disloyal ones will bypass anyway), consider all the possibilities to simply generate a UUID when installing an application and not make a head for yourself or people.

Answer 2

the serial number of any hardware. video card, etc.

Answer 3

It is logical that if you cannot bind something to the user's hardware, it makes sense to bind your hardware to the user's machine. If this is a commercial solution - the best option for protection is a physical key - a dongle. This is a hell of a job for the client, a rise in price for you (well, or for the client too), but it gives a clear connection with the iron, as you wanted. That is, only one computer with 1 dongle can work at the same time.
