Urgent Note for Those that Use Google Authenticator with AWS

Posted by Imran Ahmed on Wed, Sep 04, 2013 @ 08:49 AM

AWS recommends, as a rule, to secure your Amazon Web Services master account using Multi-Factor Authentication or MFA using either a hardware token or software token provided by Google Authenticator.

If you use the latter method, please stop for just a moment and take note:

In the early morning hours, AWS released an urgent advisory regarding Google’s Authenticator application for iOS devices. It appears that a recent App update by Google will wipe out any existing tokens.

This means that you will immediately lose access to any system, including AWS, for which you might be using Authenticator if you update the Google Authenticator App. At this point in time, AWS advises users not to update the app.

If you already have found yourself in this position, please contact Amazon for assistance. If you happen to subscribe to Cloud Services for AWS by Clearpath, please call our Helpdesk for immediate assistance in getting this resolved.

Amazon’s Customer Service team can be reached here.

AWS is also keeping customers advised as to any updates via their developer forum. That thread can be accessed here.
