# 启用通行密钥

### **网页端 |** 如何启用通行密钥？

#### **开始前准备**

* 使用支持通行密钥的浏览器（如 Chrome、Safari 或 Edge）
* 确保已启用设备锁（面容 ID（Face ID）、指纹（Fingerprint）或 PIN）
* 选择一个通行密钥管理器（Passkey Manager）：
  * 系统内置（例如 iCloud Passwords）
  * 第三方（例如 1Password，需安装并解锁浏览器扩展）

> 💡 **建议启用云同步。** 启用云同步不会降低通行密钥的安全性，并有助于在更换、重置或丢失设备时避免登录问题。

#### 启用通行密钥步骤（网页端）

1. 登录交易所账户，点击右上角的 **设置** 按钮，选择 **安全**。在通行密钥区域点击 **启用**。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://support.backpack.exchange/support-docs/cn/jiao-yi-suo/an-quan/tong-xing-mi-yao-passkeys/qi-yong-tong-xing-mi-yao.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.
