Gaia Support is Amazing!
So Gaia has an option for Secondary Authentication that links your account to Google Authenticator.
With this enabled, each and every time you login you are brought to this:

I had this enabled 12 June of this year.
Everything was going good until yesterday morning (4 Sept 2013) when I noticed an update to the Authenticator iOS app.
A borked update that wiped all the accounts stored!
This has been reported by several tech sites already:
[Link] TechCrunch: Don’t Install The Google Authenticator For iOS Update, Unless You Want Your Stored User Accounts Wiped
[Link] TechHive: Borked Google Authenticator update wipes iOS user data
[Link] The Next Web: Google confirms it’s working on an update to fix Google Authenticator for iOS data losses
Of course this news was too late for me, I had already updated!
After a day of panic I filed a support ticket with my mule account around 12:40AM Eastern last night.
First answer was at 1:04PM Eastern earlier today, suggesting a password reset, which failed.
My password wasn't the problem, I still had access the email my account was linked to (it's now linked to another of my emails due to the support ticket), and I could reset the password as many times I wanted to no avail. The problem I was having can be seen in the image above.
Each and every time I try to login, it would ask for the required Secondary Auth Token provided by the Google Authenticator app, but since the app itself was wiped and I have been and is still unable, even as I'm typing this, to restore anything to it, that meant I was forever semi-locked out of my account.
I say semi-locked out because I could still login via the Gaia On The Go mobile app. The mobile app however is very limited in it's functions compared to accessing the full site via your browser.
So I explained about it still asking for the Secondary Auth Token and within about 20 minutes was another reply from support saying "Please try accessing the account again by simply attempting to log in. You should run into no problem now."
And here I am again, with full access to my account again!
All in all, it took about an hour from the first contact with support since starting the ticket to the solution that resolved my problem.
Needless to say, Secondary Authentication will remain disabled.
