If it keys off the MAC for a pseudo password, how can this scheme work if you swap to a new phone?

- kapnobatairza 14y agoWith WhatsApp you have one account per phone number that you activate on each phone through SMS authentication. So if I installed WhatsApp to my iPhone 4 under number 917-555-5555, WhatsApp will then text that number with an activation code and when I enter that activation code in the WhatsApp app, it ties that number to my phone with that phone's MAC address/IMEI. If I then upgraded to the iPhone 5 under the same number, the process repeats itself and now ties that number to the iPhone 5 with it's MAC address/IMEI. I will now lose access to WhatsApp on that number on my iPhone 4.
