The password is generated using the `pw` tool provided by mosquitto-go-auth, which is included in the image at `/opt/bin`. It can be used either within the container using `docker exec -it <mosquitto-container> /opt/bin/pw`. You may also try to copy it from the container onto your Linux host. It should run, since it is only linked against typical Linux libraries, however, I wouldn't do that.
