I know that this is an old thread, but I'm posting this to help anyone who may come across this thread. I forgot to deactivate my SMS authentication when I switched phone providers. I sent them a ticket when I couldn't log in due to this and they deleted the authentication in 3 days and sent me an email letting me know. The key is to provide as much info as possible. I gave them 3 of my characters names, my old cell phone #, my GW2, HoT & PoF serial codes. I was told that with all that info it proved that I was the owner of the account and helped with a speedy resolution. Always give as much info as possible!
