![]() Google Group Product Manager Christiaan Brand tweeted that end-to-end encryption (E2EE) will be made available for Google Authenticator down the line, but they are rolling out this feature carefully. Meaning that if you lost your device and the passphrase, you would lose all access to your accounts. Google’s primary objection to this method was that it heightens the risk of users getting completely locked out of their own data. This would introduce an extra safeguard that makes them accessible only to their owner. The likelihood of someone stealing the secret seeds from Google’s servers is relatively small, but since it is better to be safe than sorry and one problem less is always good to have, users asked Google to add a passphrase to protect the secrets. This would mean that in case of a data breach or if someone obtains access to your Google Account, all of your OTP secrets would be compromised, and they would be able to generate OTPs as if they were you. They analyzed the network traffic that occurs when the app syncs the secrets, and found out that the traffic was not end-to-end encrypted. Shortly after the new feature was rolled out, Mysk’s security researchers advised against turning on the new feature. Since OTPs in Google Authenticator were previously only stored on a single device, a loss of that device locked you out of any service where you used it to log in. Some apps you can choose are Google Authenticator, Microsoft Authenticator, Duo, Twilio Authy. If you don’t have an Authenticator App, you can download one from the App Store. ![]() To enable 2-Step Verification by Authenticator App, you must have an Authenticator app on your mobile device. This allows users to create a backup which they can use if their device is lost, stolen, or damaged. Set up 2-Step Verification by Authenticator App. On April 24, 2023, Google announced an update across both iOS and Android, which added the ability to safely backup the secrets used to generate OTPs to your Google Account. Although it’s made by Google it’s not limited to Google’s own services, but can also be used with Facebook, Twitter, Instagram, and many more. Google Authenticator is one of the most well-known authenticators. They serve as an additional form of authentication by proving that you have access to the device generating the OTP. These OTPs are only valid for a short period and are generated on demand. Google Authenticator is an authenticator app used to generate access codes, called one-time passwords (OTPs). The search giant recently introduced a feature that allows users back up two-factor authentication ( 2FA) tokens to the cloud, but the lack of encryption caused some commentators to warn people off using it. Following criticism, Google has decided to bring end-to-end encryption (E2EE) to its Google Authenticator cloud backups.
