I was having problems and decided to go to mobile authentication. So, I turned off my key-ring authenticator I have had since it first came out, paid for and everything. Downloaded the mobile app from Blizzard and installed it. When it asked for email, put it in and the correct password, checked and triple checked. The app keeps telling me “incorrect password”. Yet it is the one I used to get on here. Help please sometime soon. When I go to activate it online, it keeps asking for a serial number. Not sure just what that number would be, my phone serial number, my social security number, or my old Navy serial number?? Wondering…
