Google Authenticator introduces cloud backup and syncing for 2FA codes.

Google Authenticator has released an update for Android and iOS that allows users to back up their two-factor authentication one-time passwords (OTPs) to their Google Accounts and have multi-device support. This update addresses one of the biggest critiques of the app, which was the inability to back up one-time 2FA codes and the lack of multi-device support. With this feature, users can now synchronize their 2FA codes with their Google account and add their 2FA codes to multiple devices.
