![]() ![]() ![]() ![]() The transmission only took place via TLS, so that a man-in-the-middle attack cannot read the data. When Mysk analyzing the network traffic during the backup of the passkey, it was noticed that this data is not end-to-end encrypted. Mysk (iOS developer and security researcher) points this out in a tweet. Unfortunately, the Google developers fell a bit short, because the transfer of the passcode through the Authenticator app to the user's Google account is unencrypted and thus potentially insecure. Geht das Gerät mit der installierten Google Authenticator-App verloren, lässt sich der benötigte Passcode mit einem neuen Gerät über das zugeordnete Google-Konto synchronisieren. Nach einem Update der Google Authenticator-App haben die Nutzer nun optional die Möglichkeit, den auf dem Gerät vom Google Authenticator gespeicherten einmalige Code (Passcode) mit ihrem Google-Konto zu sichern. If the device with the installed Google Authenticator app is lost, the required passcode can be synchronized with a new device via the assigned Google account. While there are security codes during setup that can be used to unlock the whole thing – they are often lost or misplaced.īased on a lot of user feedback, Google then announced a new feature on Apin the article Google Authenticator now supports Google Account synchronizationAfter an update of the Google Authenticator app, users now have the option of backing up the unique code (passcode) stored on the device by Google Authenticator with their Google account. Then the unique code (passcodes) stored on the device by Google Authenticator is lost, and users can no longer log in to the services in question, with two-factor authentication (2FA) set up in Authenticator. The problem with this approach, however, is that dealing with the Google Authenticator can become quite complex if the device on which the app is installed is stolen, lost or simply broken. The app is intended to increase user security when logging into online accounts. The Google Authenticator app is available for both Android and iOS. Google Authenticator was released in 2010 as a free and easy option for websites that require two-factor authentication (2FA). I'm puzzled as to how this could have happened.Backup of passcodes in the Google Account I've already read the Apple support pages and I don't think I can restore. What might have caused this so that I can prevent this in the future? This seems like a very sensitive or buggy feature - or the interoperability of the codes across devices, combined with icloud backup, is buggy.Īny help would be appreciated.Is there any way to retrieve the authenticator codes from a iphone/ipad backup?.Now, I went to use the authenticator app and only a subset of the codes remain on each device- and the ones that remain are not even the same across all devices. I updated one of the phones and the ipad to iOS/IpadOS 15.0.2. I then confirmed on each device that it had the same list of authenticator codes as the others.Īfter all lists were de-duped. So I went through each device and deleted the duplicate set. each device had a couple lists of the same codes). I noticed that each device had duplicate entries of the same codes (i.e. I have Google Authenticator replicated acc\ross two iphones and an ipad. ![]()
