This article will guide you on the process to set up a JupyterLab Environment on Ubuntu and made it accessible remotely.
The JupyterLab Credential Store uses a password that you set upon first use. Each credential is encrypted with a hash of your password. The encrypted credentials are stored in the credentialstore file in the #directory you start #JupyterLab from.
You can also create new #environments from within Jupyter Notebook (home screen, Conda tab, and then click the plus sign). And you can create a notebook in any environment you want. Select the "Files" tab on the home screen and click the "New" dropdown menu, and in that menu select a Python environment from the list.
