Edy I think a lot of people are going to be totally confused by this because the authenticator app says it's for use with Google accounts. It doesn't mention that it can be used on third party sites or that you don't have to have a Google account to get the number. It would be nice if you mention on the page you link to that you don't need to have a Google account to use the code on Gaia. Right now Google mentions nothing about using their authenticator with third party sites.
First off, I couldn't get my iPhone to recognize the barcode thing, so I ended up typing in the code by hand, which is why I don't have a picture of anything~
I'm on an iPhone 4S and I download the app and everything, however I named the account something I didn't like after I had already authorized it and everything, so I figured I could just delete it and re-do it.
No. sad So, basically, to log into my account I need a code I no longer have access to.
