Please be warned that if you don't wait until a Windows app comes out and sign up with your Android or IOS device now you will not be able to switch devices later. I found this out the hard way. When I started playing SWTOR and set up the Authenticator I set it up on my iPad. Now that i have an android phone I wanted to set it up there instead. YOU CAN NOT MOVE IT!! I guess it's on the "something to be fixed" list, but I doubt it's anyone's TOP priority.
