Hi @Mrbobbyboo , Are you referring to the Google Account PIN or the Google Authenticator app? And any devices in mind that you're wanting to transfer from and to?
No worries!
I don't use the app, so I can't say for sure whether it will or won't automatically transfer over just by using something like Smart Switch. But Google's Support article on it suggests that it won't, and that you'd need to transfer it manually using the steps it advises: https://support.google.com/accounts/answer/1066447?hl=en&ref_topic=2954345&sjid=4460881485347800019-...
