I used to work for Vivint. They had an app to which would link my account only to my device. If i downloaded the app to another device even If I used the same username/password. it won't work. I would like to know how they did this. What part of the Phone made the device unique app. was it a Serial Number or how. I would be using for my app idea a php backend on a server. which will read the information. ANy help would be greatly appreciated.
thanks.
