Google Authenticator 5.10 includes the ability to import and export 2FA/2SV accounts between devices. The feature is available in the latest version (5.10) of the app on Android. The bad news is that it is only available on the Android version, and Google has not stated if an updated version will be released for iPhone users. BleepingComputer has contacted Google to see if they have plans on releasing an iOS version but had not heard back. For iPhone users, you are still stuck on the same version released in 2018.
