Jupyter notebook warning

I’m having a warnings on the NotebookApp when running docker Kaggle/python on Ubuntu:

  1. Docker version 20.10.1 (build 831ebea) installed on Ubuntu 20.04.
  2. kaggle/python (993897c5431c) pulled docker pull kaggle/python
  3. Different running options:
docker run -v ${PWD}:/tmp/working -w=/tmp/working -p 8888:8888 --rm -it kaggle/python bash -c "jupyter notebook --notebook-dir=/tmp/working --ip='*' --port=8888 --no-browser --allow-root"
  1. are giving me the same warning:
**[W 12:40:11.750 NotebookApp] Config option `allow_remote_access` not recognized by `NotebookApp`.  Did you mean one of: `allow_credentials, allow_root`?**

[I 12:40:11.764 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret

**[W 12:40:12.016 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.**

**[W 12:40:12.016 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using authentication. This is highly insecure and not recommended.**

It seems password is not requested so authentication is not activated...

what can i do? 

Thanks for your time
