Great move from Google
It is very important that the only password tools used for two-step verification can be backed up, because when switching to a new device or reinstalling the tool, it is necessary to cancel all codes from the relevant site and set them again.
Single password tools like Authy have long backed up codes to the cloud and allowed them to be used on multiple devices, but Google was very strict about this, and it was the issue that especially those who were familiar with the crypto money world complained about the most.
As of this week, the iOS and Android Google Authenticator application started to offer the opportunity to backup codes to the cloud account. Thus, users will be able to easily transfer their data to another device, but it is stated that the condition of use on a single device continues.
