Two-factor authentication allows you to reinforce security on your PlayFab Game Manager account by adding one more step to the authentication process. It does so by adding a device-factor to the authentication process, which only allows you to authenticate, if you possess a certain device specifically registered for this purpose. ## Configuring two-factor authentication Install a **Two-Factor Authentication** app to your device. You can search on your own application, or select your platform from the following list: * [iPhone, iPad, and iPod Touch](https://itunes.apple.com/us/app/google-authenticator/id388497605?mt=8) * [Android phone or tablet](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2) * [Windows phone or tablet](https://www.windowsphone.com/store/app/authenticator/e7994dbc-2336-4950-91ba-ca22d653759b) The steps are basically similar on all the platforms. This example shows an Android-based device, and a Google Authenticator application. Once the application is downloaded; * Open it and follow the instructions. * Select the **Begin** button **(1)**.

Game Manager - My Profile - Two-Factor Authentication Once this is done, you will obtain a two-factor code. Google - Authenticator - Confirm verification code Head back to the **Profile** settings in the PlayFab **Game Manager**: * Enter the **code** you received **(1)**. * Select **Save Profile** button **(2)**. Game Manager - My Profile - Enter Two-factor code ## Testing Log out of your PlayFab account and try to log in again. The first step of the authentication process will look normal (see example provided below). PlayFab - Login Screen The second step will require you to use your two-factor code. The code is available at any time, and you can access it using the application you installed on your device.
