# Vercel Deployment Password Protection
This document explains how to enable and use the password protection feature for your Vercel deployment. This feature uses Next.js Middleware and Vercel API Functions with an elegant authentication page to restrict access to your deployed application.
## How it Works
When password protection is enabled, users attempting to access your Vercel deployment will be intercepted by middleware:
- If they are not authenticated, they will see an elegant password verification page.
- If they enter the correct password, they will be granted access to the application. A cookie is set in their browser to remember their session, so they won't need to re-enter the password for a certain period (e.g., 7 days) or until they clear their cookies.
- If they enter an incorrect password, they will be shown an error message and prompted to try again.
- The verification page automatically displays in either Chinese or English based on the user's browser language settings.
This protection works entirely through Next.js Middleware and Vercel API without modifying the main web application code.
## Setup Instructions
1. **Set the Access Password Environment Variable:**
* Go to your project settings in Vercel.
* Navigate to "Settings" -> "Environment Variables".
* Create a new environment variable named `ACCESS_PASSWORD`.
* Set its value to the password you want to use for accessing the site. Choose a strong, unique password.
* Ensure the variable is available to all environments you wish to protect (Production, Preview, Development).
* When you add or change environment variables, Vercel will prompt you to redeploy your project. Follow the prompts to complete the redeployment.
2. **Accessing Your Protected Site:**
* Once the `ACCESS_PASSWORD` is set and the project has redeployed, try accessing your Vercel deployment URL.
* You should see a password verification page.
* Enter the password you configured in the `ACCESS_PASSWORD` environment variable.
* Upon successful authentication, the page will reload and show the main application.
## Technical Details
- **Technology Used:**
- Next.js Middleware (`middleware.js`) for intercepting all page requests and serving the verification page
- Vercel API Functions (`/api/auth.js`) for server-side password verification
- Language-adaptive verification page (automatically displays in Chinese or English based on browser language)
- **Cookie Name:** `vercel_access_token` (This cookie stores the access password. It's HttpOnly, Secure in production, and SameSite=Strict).
- **Password Storage:** The actual password is only stored as an environment variable in your Vercel project settings. It is not hardcoded in the application.
- **Bypassing Protection:** If the `ACCESS_PASSWORD` environment variable is not set or is empty, the password protection will be bypassed, and the site will be publicly accessible. This allows for easy disabling of the feature if needed.
- **Non-invasive Implementation:** This protection is completely independent of the main web application code. All logic is contained in the `middleware.js` and `api/auth.js` files.
- **Security Note:** This is a presentation-layer protection that can be bypassed by users who disable JavaScript or directly access API endpoints. For stronger security, consider using Vercel's built-in password protection feature.
- **Multi-language Support:** The verification page automatically detects the browser's `accept-language` header to display a Chinese interface for Chinese users and an English interface for users of other languages.
## Troubleshooting
- **Password verification page doesn't appear:**
* Ensure the `ACCESS_PASSWORD` environment variable is correctly set in Vercel and that the project has finished redeploying.
* Check the browser console for any errors related to the middleware or authentication API.
* Verify that the `/api/auth` endpoint is working by accessing it directly.
- **Incorrect password error, even with the correct password:**
* Double-check the value of the `ACCESS_PASSWORD` environment variable for typos or extra spaces.
* Try clearing your browser cookies for the site and attempting again.
* Check the browser network tab to see if the API call is successful.
- **Language display issues:**
* If the verification page language doesn't match your browser settings, confirm that your browser has the correct preferred language settings.
* You can switch the display language of the verification page by modifying your browser's language settings.

# Vercel 部署密码保护
本文档说明如何为您的 Vercel 部署启用和使用密码保护功能。此功能使用 Next.js Middleware 和 Vercel API 函数,通过美观的身份验证页面来限制对您已部署应用程序的访问。
## 工作原理
启用密码保护后,尝试访问您的 Vercel 部署的用户将被中间件拦截:
- 如果他们未经身份验证,将看到一个美观的密码验证页面。
- 如果他们输入正确的密码,他们将被授予访问应用程序的权限。一个 Cookie 会被设置在他们的浏览器中以记住他们的会话,因此他们在一段时间内(例如 7 天)或直到他们清除 Cookie 之前无需重新输入密码。
- 如果他们输入错误的密码,他们将看到错误消息并被提示重试。
- 验证页面会根据用户浏览器语言设置自动选择显示中文或英文界面。
此保护完全通过 Next.js Middleware 和 Vercel API 实现,无需修改主要的 web 应用程序代码。
## 设置说明
1. **设置访问密码环境变量:**
* 进入您在 Vercel 中的项目设置。
* 导航到"Settings"->"Environment Variables"。
* 创建一个名为 `ACCESS_PASSWORD` 的新环境变量。
* 将其值设置为您希望用于访问站点的密码。选择一个强壮且唯一的密码。
* 确保该变量在您希望保护的所有环境(生产、预览、开发)中都可用。
* 当您添加或更改环境变量时,Vercel 会提示您重新部署项目。请按照提示完成重新部署。
2. **访问受保护的站点:**
* 一旦设置了 `ACCESS_PASSWORD` 并且项目已重新部署,请尝试访问您的 Vercel 部署 URL。
* 您应该会看到一个密码验证页面。
* 输入您在 `ACCESS_PASSWORD` 环境变量中配置的密码。
* 成功验证后,页面将重新加载并显示主应用程序。
## 技术细节
- **所用技术:**
- Next.js Middleware(`middleware.js`)用于拦截所有页面请求并提供验证页面
- Vercel API 函数(`/api/auth.js`)用于服务端密码验证
- 自适应语言的验证页面(根据浏览器语言自动显示中文或英文)
- **Cookie 名称:** `vercel_access_token`(此 Cookie 存储访问密码。它是 HttpOnly,在生产环境中是 Secure,并且 SameSite=Strict)。
- **密码存储:** 实际密码仅作为环境变量存储在您的 Vercel 项目设置中。它没有硬编码在应用程序中。
- **绕过保护:** 如果未设置 `ACCESS_PASSWORD` 环境变量或该变量为空,则密码保护将被绕过,站点将公开访问。这允许在需要时轻松禁用该功能。
- **非侵入性实现:** 此保护完全独立于主要的 web 应用程序代码。所有逻辑都包含在 `middleware.js` 和 `api/auth.js` 文件中。
- **安全说明:** 这是表现层保护,可以被禁用 JavaScript 或直接访问 API 端点的用户绕过。如需更强的安全性,请考虑使用 Vercel 的内置密码保护功能。
- **多语言支持:** 验证页面会自动检测浏览器的 `accept-language` 请求头,为中文用户显示中文界面,为其他语言用户显示英文界面。
## 故障排除
- **密码验证页面未出现:**
* 确保在 Vercel 中正确设置了 `ACCESS_PASSWORD` 环境变量,并且项目已完成重新部署。
* 检查浏览器控制台中是否有与中间件或身份验证 API 相关的任何错误。
* 通过直接访问 `/api/auth` 端点来验证它是否正常工作。
- **即使使用正确的密码也提示密码错误:**
* 仔细检查 `ACCESS_PASSWORD` 环境变量的值是否有拼写错误或多余的空格。
* 尝试清除站点的浏览器 Cookie,然后重试。
* 检查浏览器网络选项卡以查看 API 调用是否成功。
- **语言显示问题:**
* 如果验证页面语言与您的浏览器设置不符,请确认您的浏览器已正确设置首选语言。
* 您可以通过修改浏览器的语言设置来切换验证页面的显示语言。
如需进一步帮助,请查看项目的主 README 文件或在存储库中提交问题。
