JupyterHub user authentication

Hi all,

I need help with authenticating the jupyter hub users. There are some vulnerabilities with get method authentication. This is because when running a vulnerability tool they can show me the username and password to authenticate with the web server.

I would like to know how I can do to configure some text file in Jypyter Hub to solve this user authentication problem, or what else I could do to avoid this security problem.

Thank you very much!
