Restore Google Authenticator accounts from ADB backup About a month ago I accidently dropped my Nexus 4. Altough it dropped from only about half a meter- the screen broke and the multitouch stopped working too. I was lucky (and smart :P) enough to take a backup before it happend, so I can switch to a new device instead of fixing the N4 screen to recover the data on it. However, I enabled 2-factor auth on my GitHub account, and it was connected to the Google Authenticator app. When I enabled it, I was dumb and didn't download the recover keys- the only way to recover the account. It means that resotring the Google Auth app from the ADB backup is the only way to recover my account, but there's a little problem: I have no android device right now, and it may take some time until i'd buy a new one. So, the question is- is there any way to recover my account from ADB backup of the Google Auth app without an Android phone?

Thanks! :)
You cannot get the recovery keys (which are used to create backup codes) from adb backup of Google Authenticator because they do not exist in that backup. Adb backup of Google Authenticator only backup the user preferences of that app. 

Furthermore, if you took a single adb backup, hoping all apps would have been backed up that way, than I'm afraid even the user preferences were not backed up. A specific flag is used for Authenticator when backing up through adb. Without that, the app cannot be backed up. You can read more on that in my answer here.
