Google Authenticator Introduces Cloud Sync for Two-Factor Codes

Google has updated its Authenticator app for Android and iOS with an account synchronization option that allows users to back up their time-based one-time passwords (TOTPs) codes to the cloud. The cloud sync feature is optional, meaning users can opt to use the Authenticator app without linking it to a Google account. The update finally brings it in line with Apple's iCloud Keychain and addresses a long-standing complaint that it's tied to the device on which it's installed, making it a hassle when switching between phones.
