Use Authy for 2FA instead: https://authy.com

Authenticator is perfectly safe to use, but your seeds are not backed up, nor is your authenticator account able to be used across multiple devices. This means that if you lose your device, you will no longer have access to any of your protected accounts, and you will not be able to restore the data from your next device, even if you use a full backup to restore.

Authy can be used anywhere that Authenticator is suggested to be used, and you can retrieve a backup if you ever lose your device.
