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.

    I was searching for a Google authenticator replacement (quite frankly I don't like the idea of transmitting any data to Google) and this works great. I use it with a non Microsoft app I created that uses TOTP authentication and have no issues. I would, however, like to be able to delete or inactivate entries that are no longer valid so they stop generating codes when I open the app - 4 stars for that inconvenience.

    Great application. Keeps all my accounts (Google, Microsoft, etc.) secure.

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

    Codes don't fricking work to authenticate logins, but if you like random numbers, you'd like the app.

    Nice security feature, but scanning the QR code when it's on your device screen is less than ideal.
