+# 宝塔一键登录临时时效改为 24 小时
+
+**日期**：2026-06-21
+
+## 摘要
+
+一键登录生成临时 `tmp_token` 时，`expire_time` 设为当前时间 + **86400 秒**（24 小时）；SSH 回退不再调用 `tools.py get_temp_login_ipv4`（固定 3 小时），改为远程执行同等逻辑并传入 TTL。
+
+## 动机
+
+用户希望登录后面板会话与临时链接上限为 24 小时；宝塔默认 3 小时，且 `tmp_login_expire` 为生成链接时的绝对时间。
+
+## 涉及文件
+
+- `server/infrastructure/btpanel/constants.py` — `BT_TEMP_LOGIN_TTL_SECONDS = 86400`
+- `server/application/services/btpanel_service.py` — API `set_temp_login` 传 `expire_time`，解析 `token` 拼 URL
+- `server/infrastructure/btpanel/ssh_login.py` — `build_ssh_temp_login_command`
+- `tests/test_btpanel_temp_login_ttl.py`
+
+## 迁移 / 重启
+
+仅 API 变更；部署后端镜像即可，前端无改动。
+
+## 验证
+
+```bash
+.venv/bin/pytest tests/test_btpanel_temp_login_ttl.py tests/test_btpanel_ssh_login.py -q
+```
+
+生产：`POST /api/btpanel/servers/{id}/login-url` 后登录，约 24 小时内不应提示「临时登录已过期」（仍受面板 `session_timeout.pl` 约束）。
