Finally, 2Fa backup codes are safe. Google Authenticator with 2FA synchronization in Google Account, is perhaps the most important update to Google to an application this year.
Like Apple, Google has always emphasized security and insisted that for all accounts that use services such as: Google Ads, Google Merchant and others to use Authentication with two factors. The problem has always been the application Google Authenticator, provided by Google itself. Application that types the authentication tokens but did not allow a cod backup 2FA.
Personally, I preferred the application 2FA Authenticator (2FAS) Instead of Google Authenticator, precisely for the Backup support in iCloud of codes 2FA.
Fortunately, after many years and many codes 2FA lost, Google came up with an important update of the application Google Authenticator. Support for the synchronization of the credentials 2FA in Google Account.
Google Authenticator with 2FA synchronization in Google Account
Cloud syncing: Your Authenticator codes can now be synced to your Google Account and across your devices, so you can always access them even if you lose your phone.
However, it remains an inconvenience for iPhone and iPad users. Google Authenticator synchronizes the codes 2FA In the Google cloud, so to start synchronization, you must authenticate in your Google account. At the 2Fas application, things are much easier. If you download the 2FAS application on an iPhone or iPad, it will synchronize the 2FA codes in iCloud, without the need for the user.

It is a very important update anyway. I know people who have lost access to various accounts because they lost their phone or reinstalled the operating system, forgetting to export to the 2Fa credentials of Google Authenticator.
