Simple, works well... until you have to move to a new device

Google, seriously, what are you thinking? If you want people to use this app for more than just the gmail account, just build a back up option. I have been used your app just fine and i changed devices with iCloud back up and restore and it was fine. Now Apple support advised me to do clean restore and I wanted to back up and restore the Authenticator app separately... good luck with that! I had to manually switch all my accounts to LastPass authenticator which does have a built in back up option.
