My only concern with this is if its handled similarly to SWTOR's token phone app. If you factory reset, root, flash a new ROM, switch phones etc you cannot simply just reinstall the app and have it magically work. With SWTOR you also cannot request they remove the token from your account through live chat or email, it has to be over the phone. Now you can say, "so just call them and stop complaining" and in theory that's fine. The problem is if SE is anything like Bioware in their phone support, no one is going to want to have to deal with it. I sat waiting for an hour on hold for someone before I gave up and decided it wasn't worth giving SWTOR another chance at that rate.

I ~love~ the idea of the convenience of having it on my phone. I do not love the idea of not being able to play because I decided to try out a new ROM/dropped my phone in a puddle and customer support isn't open on weekends.

SE, can you give us a clearer idea of what will happen with the app in these situations?
