title: Passwordless User authentication with a Django or just any REST API system
body: <p>I am implementing a webservice with a bunch of REST API. These REST API will all be invoked from a python command line interface script. </p>
  
  <p>When a userA, logged in as himself on a unix system, invokes that CLI python script, I would like the script to be able to invoke the REST API through the python HTTP client, but do it without having to use a password.</p>
  
  <p>Since he is already, authenticated as himself on the linux.</p>
  
  <p>How can this be implemented? 
  Are there any Django packages/documentation that help with it?</p>
