Hello fellow Djangonauts 
I know this is not something new, but we decided to write an article, sharing our latest experience of simply adding Google login to an existing Django / Django Rest Framework application, without adding one of the big and popular 3rd party packages.
The case is that you can already have an existing auth system and you may not want to make drastic changes, only to accommodate simple Google login. And the good part is - it works with SPAs too/
You can check the blog post here - https://www.hacksoft.io/blog/adding-google-login-to-your-existing-django-and-django-rest-framework-applications
If this can be helpful to someone else - even better.
Happy reading
