Implementing Google Authentication and Fetching Mails from Scratch Using Python Django

Google Authentication and Fetching mails from scratch means without using module which has already set up this authentication process. Let’s create Django 2.0 project and then implement Google authentication services and then extract mails. We are doing extract-mail just to show how one can ask for permission after authenticating it. We’ll be using Google API python client and oauth2client which is provided by google. Sometimes, it really hard to implement this Google authentication with these libraries as there was no proper documentation available.
