Jupyterhub access

Hi, I’m new to docker and I would like to ask what is the default username and password. In addition, I would like to know how I can add new user. when i use the user name is jovyan and the password is jupyter it didn’t work , I don’t know if its the correct login access. the jupyter docker is Docker Hub

Thank you

There is not a default username or password for JupyterHub. If you are using the jupyterhub/jupyterhub docker image, you must configure an Authenticator, which is how you set usernames and passwords (or more commonly: use an external source of authentication that does not involve passwords, such as OAuth).
