# 2FA code

2fa code 是一个用于根据提供的原始安全密钥,自动生成随时间变化的六位数双重验证码(类似手机上的 Google Authenticator 或 Authy 应用)的操作。

该操作在 MMO 场景中极其重要,可以帮助自动通过登录 Facebook、Google、X(Twitter)、Discord、Coinlist 等账户时的安全验证步骤,而无需打开手机手动输入。

#### 配置参数:

* Secret key:原始安全密钥(一串较长的字母和数字组合,通常在您于网站上开启双重验证安全功能时获得)。
* Output variable:用于存储生成的六位数验证码的变量名称。

#### 实际示例:登录 Facebook 时自动填写 2FA 验证码

假设您在 Excel 中保存了一个 Facebook 账户的数据,其中该账户的双重验证密钥(Secret key)列的值为:`JBSWY3DPEHPK3PXP`。

当浏览器跳转到 Facebook 登录页面,填写完用户名/密码后,Facebook 会要求输入六位数验证码才能进入账户。您可以按照以下方式配置自动处理流程:

* 配置方法:
  * 调用 2fa code 操作。
  * Secret key:填入字符串 `JBSWY3DPEHPK3PXP`(或传入从 Excel 文件读取出的包含该字符串的变量)。
  * Output variable:将变量命名为 `$twoFACode`。
* 结果:系统会根据时间加密算法立即计算出当前的六位数验证码(例如:`482915`)并存入 `$twoFACode` 变量中。在此操作之后,您可以继续调用 Key press 命令,将 `$twoFACode` 变量传入 Facebook 的验证码输入框中,即可成功登录。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.gpmautomate.com/automate-zh/action-shi-yong-zhi-nan/text-and-number/2fa-code.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
