Not sure what's going on. Just got my droid razr maxx yesterday and today I just enabled google 2-step authentication. I've added an application/site password (the long random characters) and it worked perfectly on my phone. However, a few minutes later, it tells me that my username or password is incorrect. I'm not sure what the hell is going on... How come it refreshes and allows me to even see new email, and then turns around and tell me that credentials are invalid?
