## Environment variables
Also go2rtc support templates for using environment variables in any part of config:
There is support for loading external variables into the config. First, they will be attempted to be loaded from [credential files](https://systemd.io/CREDENTIALS). If `CREDENTIALS_DIRECTORY` is not set, then the key will be loaded from an environment variable. If no environment variable is set, then the string will be left as-is.
```yaml
streams:
camera1: rtsp://rtsp:${CAMERA_PASSWORD}@192.168.1.123/av_stream/ch0
rtsp:
username: ${RTSP_USER:admin} # "admin" if env "RTSP_USER" not set
password: ${RTSP_PASS:secret} # "secret" if env "RTSP_PASS" not set
username: ${RTSP_USER:admin} # "admin" if "RTSP_USER" not set
password: ${RTSP_PASS:secret} # "secret" if "RTSP_PASS" not set
```
