# 双重身份验证

> 通过在设备上配对身份验证器应用以启用双重登录验证，为你的 PlayFab Game Manager 帐户添加额外一层安全性。

双重身份验证允许你通过在身份验证过程中添加一个额外步骤，来增强 PlayFab Game Manager 帐户的安全性。

它通过在身份验证过程中添加一个设备因素来实现这一点，这只有在你拥有为此目的专门注册的某个设备时，才允许你进行身份验证。

## 配置双重身份验证

在你的设备上安装一个**双重身份验证**应用。你可以搜索你自己的应用，或者从以下列表中选择你的平台：

* [iPhone、iPad 和 iPod Touch](https://itunes.apple.com/us/app/google-authenticator/id388497605?mt=8)
* [Android 手机或平板](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2)
* [Windows 手机或平板](https://www.windowsphone.com/store/app/authenticator/e7994dbc-2336-4950-91ba-ca22d653759b)

所有平台上的步骤基本相似。此示例展示了一台基于 Android 的设备和 Google Authenticator 应用。

下载该应用后：

* 打开它并按照说明操作。
* 选择 **Begin** 按钮 **(1)**。

如果有的话，按照该应用的教程进行 **(1)**。

* 然后选择两个选项之一来添加你的 PlayFab 帐户：

* 扫描**二维码 (1)**。

* 或手动输入**密钥 (2)**。

无论你选择哪个选项，都请转到 PlayFab 网站并导航到 **Game Manager**。在 **Dashboard** 选项卡上：

* 选择 **Account** 面板 **(1)**。
* 然后选择 **My Profile (2)**。

**Account** 设置将打开。

* 验证 **Enable two-factor authentication** 复选框已被选中。
* 根据你选择的选项，使用**代码 (1)** 或**二维码 (2)** 使用你设备上的应用添加新帐户。

完成后，你将获得一个双重身份验证代码。

返回到 PlayFab **Game Manager** 中的 **Profile** 设置：

* 输入你收到的**代码 (1)**。
* 选择 **Save Profile** 按钮 **(2)**。

## 测试

退出你的 PlayFab 帐户并尝试再次登录。身份验证过程的第一步看起来会很正常（请参阅下面提供的示例）。

<img src="https://mintcdn.com/microsoft-4404708b/Oa_DP1q6U1lat7c2/images/playfab/identity/dev-identity/authentication/playfab-login-screen.png?fit=max&auto=format&n=Oa_DP1q6U1lat7c2&q=85&s=752c44de2c42fa2812bf1a1c42804e84" alt="PlayFab - Login Screen" width="1144" height="699" data-path="images/playfab/identity/dev-identity/authentication/playfab-login-screen.png" />

第二步将要求你使用双重身份验证代码。该代码随时可用，你可以使用安装在设备上的应用访问它。

<img src="https://mintcdn.com/microsoft-4404708b/Oa_DP1q6U1lat7c2/images/playfab/identity/dev-identity/authentication/playfab-enter-two-factor-token.png?fit=max&auto=format&n=Oa_DP1q6U1lat7c2&q=85&s=501a24afaeb3d28dd70b94e661198a6d" alt="PlayFab - Enter Two-factor token" width="767" height="560" data-path="images/playfab/identity/dev-identity/authentication/playfab-enter-two-factor-token.png" />

一旦输入正确的双重身份验证代码，你应该已登录。

至此完成了为 PlayFab 设置双重身份验证。
