# 密码说明（Password Description）

若仅设置了管理员密码，则仅限制进入固件设置程序（BIOS 或 UEFI）。必须输入管理员密码才能读取和修改 BIOS 设置。

若仅设置了用户密码，则此为开机密码，需在开机进入 Windows 或进入 BIOS 时输入此密码。在 BIOS 设置中，使用者将拥有管理员权限。

如果同时设置了管理员密码和用户密码，进入 BIOS 设置时，必须输入管理员密码才能读取和变更 BIOS 设置。若输入的是用户密码，仅能浏览而不能修改 BIOS 设置。

只有当设备处于未设置 BIOS 密码的状态时，才可以设置新的 BIOS 密码。

密码长度要求如下：

最短长度：2

最长长度：20

如果确认不再使用密码，请在 New Password（新密码）字段中保留空白（直接回车即可）。清除密码时，系统将提示是否确认清除密码，请点击 OK。

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://book.bsdcn.org/bios/security-an-quan/password-description.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
