# 为品牌账户管理 2FA

[账户管理员](/brand/zh/what-would-you-like-to-learn-about/account-administration/account-settings/invite-and-manage-users/understanding-user-management-as-a-brand.md) 可要求所有 impact.com 品牌账户成员在从新设备登录时使用双重身份验证 (2FA)。对 2FA 有疑问？请查看我们关于 [双重身份验证常见问题](/other/zh/reference-documentation/two-factor-authentication-faqs.md).

当您受邀加入账户且注册方式需要使用用户名和密码时，系统会自动为您启用 2FA，且默认验证方式将设置为电子邮件。

启用 2FA 后，用户体验如下：

* 首次登录时，账户成员会通过短信、电子邮件或身份验证应用在其移动设备上收到验证码。
* 账户成员成功通过验证后，其设备将自动保存为受信任设备——这意味着他们在后续登录时无需再使用 2FA。只有在设备发生变化或检测到异常活动时，系统才会再次要求账户成员使用 2FA。
* 账户成员可在 impact.com 用户资料界面管理已保存的设备。

#### 为登录启用 2FA

这将为所有登录您品牌账户的账户成员启用强制双重身份验证。

## 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://help.impact.com/brand/zh/what-would-you-like-to-learn-about/account-administration/account-settings/invite-and-manage-users/manage-2fa-for-brand-accounts.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.
