 在 **系统配置 → HTTP Basic Auth** 中填写独立的验证用户名和密码，打开「启用访问验证」并点击「保存访问验证」。默认关闭，保存后立即生效，无需重启；密码至少 8 位、最多 72 字节，用户名不能包含冒号。
 
-开启后，访客先完成浏览器原生账号密码验证，再进入原有 ARTEX 登录页。网页、静态资源和 API 均受保护，`/api/health` 健康检查保留公开访问，但仅返回 `{"ok":true}`，不暴露应用名称或版本。版本号由需要管理员 JWT 的 `/api/version` 提供，启用访问验证后该接口同时受 Basic Auth 保护。未认证请求的 Basic Auth realm 使用通用名称 `Restricted`；通过访问验证仍需登录 ARTEX 才能使用业务 API。公网部署请通过 HTTPS 访问。
+开启后，访客先完成浏览器原生账号密码验证，再进入原有 ARTEX 登录页。网页、静态资源和 API 均受保护，`/api/health` 的 GET/HEAD 健康检查同样需要通过 Basic Auth，未认证时返回 `401`；通过后仅返回 `{"ok":true}`，不暴露应用名称或版本。健康检查不额外要求管理员 JWT；外部探针需要配置相同的 Basic Auth 凭据，例如使用 `curl --fail --user '验证用户名' http://127.0.0.1:8787/api/health` 并按提示输入密码。未启用 Basic Auth 时保留原有的无需凭据探活行为。版本号由需要管理员 JWT 的 `/api/version` 提供，启用访问验证后该接口同时受 Basic Auth 保护。未认证请求的 Basic Auth realm 使用通用名称 `Restricted`；通过访问验证仍需登录 ARTEX 才能使用业务 API。公网部署请通过 HTTPS 访问。
 
 从仍使用 `/api/health` 读取版本的旧版网页升级到此版本时，旧页面可能无法自动判断升级完成；服务重启后手动刷新页面即可。新版网页的版本显示和升级轮询均使用 `/api/version`。
