I don't really see the point of this, and it seems to defeat the purpose of an authenticator which is to require a separate device to access your WoW account to make it more secure?

So sure I could put this on a USB key or whatever but surely it is just as easy to use my mobile phone? Its free on iOS and Droid anyway?

Glad you had fun doing it I guess - find all the windup and your million e-mail addresses at the top of the post quite amusing. Classic overachiever if I ever saw one.
