If you haven't done so yet, create an Auth0 application at https://auth0.com/ and configure it following the instructions there. We switch need to install some dependencies in the project. 

Update your virtual environment or Docker project's requirements to include the Auth0 dependencies, as follows:

# requirements.txt or base.txt
# ...
python-dotenv~=0.8.0
requests~=2.18.0
social-auth-app-django~=2.1.0

For a virtual environment, install each of these individually using pip3 install ..., as usual. For Docker projects, make sure to build and restart your containers after updating the requirements.
