so i've factory reset my Android phone and Google Authenticator app is automatically uninstalled because of that.
The problem is when I'm install Google Authenticator app and login with the same Google account it's all gone including my FB, Heroku, etc for verifying code. I'm glad my FB 2-FA doesn't need Google Auth code.
The point is how to recover my Heroku account if I cannot login to verify my authenticator code? please help :)
