Default Use one whatsapp account on two different devices

Is it possible to use one whatsapp account on two different devices? Like on Android and laptop (Bluestack or Youwave). I already search them but I dont found to what i looking for. I want to use my whatsapp account both on my Android and latop. I read somewhere that u can do it by having the same MAC address on both devices. I use mobile network on my android and portable hotspot for wifi on my laptop. How to get the same MAC address on my laptop and android?
