# 2FA
#### 双因素认证（2FA）
所有用户账户都必须启用双因素认证（2FA），作为额外的安全控制，以降低未经授权访问的风险。它默认通过基于电子邮件的验证启用，且无法禁用。
**配置和支持的方法**
双因素认证可在您的 DataImpulse 仪表板的个人资料中进行配置 [安全设置](https://app.dataimpulse.com/account/security).
支持以下认证方法：
* 身份验证器应用程序（临时生成的代码）
* 基于电子邮件的验证 - 默认启用
您可以随时在电子邮件和身份验证器应用程序之间切换您的 2FA 方法，但 2FA 本身无法关闭——这两种方法中始终会有一种保持启用。

## 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.dataimpulse.com/dataimpulse-documentation-zh-cn/yi-biao-ban/2fa.md?ask=&goal=
```
`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.
