The Authenticator app generates security codes you can use to help keep your Microsoft account secure. You can add your Microsoft account to the app by scanning a barcode or by manually entering a secret key. The app implements industry-standard security code generation and may also work with other services and providers. You can learn more about keeping your Microsoft account secure at

** The Authenticator app is not supported for use with Windows Azure Multi-Factor Authentication. Use the Mutli Factor Authentication app for this.

    Simple and does the job well. Also works with Google accounts. I had no difficulty using the app, but a tutorial could be helpful for a non-techie user. Also, a countdown timer showing the time remaining until the code changes would be better than the progress bar.

    So easy to use, and I wish more sites supported this methodology. Any chance for an update with a transparent tile for WP8.1?

    This app works just fine in the place of the Google authenticator app.
