 ## Web-admin
 
-После первого запуска `pcatelegram_web` локальная web-admin панель ставится как `pcatelegram_web-admin.service`.
+После первого запуска `pcatelegram_web` web-admin панель ставится как `pcatelegram_web-admin.service` и слушает публично:
-
-Безопасный локальный доступ через SSH tunnel:
 
 ```bash
-ssh -L 1984:127.0.0.1:1984 root@SERVER
+http://SERVER:1984/
-open http://127.0.0.1:1984/
 ```
 
-Для public bind сначала задайте пароль через systemd override или reverse proxy:
+Логин по умолчанию: `admin`. Пароль генерируется при установке и хранится на сервере:
 
-```ini
+```bash
-[Service]
+sudo cat /root/pcatelegram_web-admin.password
-Environment=PCATELEGRAM_WEB_ADMIN_HOST=0.0.0.0
-Environment=PCATELEGRAM_WEB_ADMIN_PORT=1984
-Environment=PCATELEGRAM_WEB_ADMIN_USER=admin
-Environment=PCATELEGRAM_WEB_ADMIN_PASSWORD=change-me
 ```
 
-Без HTTPS public Basic Auth гонит пароль открытым текстом. Для постоянного доступа лучше reverse proxy с TLS.
+Для своего пароля передайте env до установки:
+
+```bash
+PCATELEGRAM_WEB_ADMIN_PASSWORD='strong-password' bash bootstrap.sh
+```
+
+Без HTTPS Basic Auth гонит пароль открытым текстом. Для постоянного доступа лучше reverse proxy с TLS, но порт `1984` открыт по умолчанию по запросу проекта.
