No token backup, use Googles new button Prompt.

Used this easy great app for years without issues... Until one day my phone accidently got drowned in water. Days later I got a new phone and my iCloud backup worked perfectly, all but the Authenticator app lost all my tokens.

This.was a good app whos time has past. Use Googles new "Google Print" instead, which simply uses the iPhone finger print button, no codes to copy/paste or enter. Googles new solution is faster, easier and more secure.
