Go beyond Django's built-in auth — learn JWT, custom email login, role-based permissions, and brute-force protection.

This article provides an in-depth exploration of Django's authentication system, covering how it works internally with authentication backends, session-based auth, and JWT-based auth using djangorestframework-simplejwt. It also covers building custom authentication backends (e.g., email login), implementing role-based permissions, and adding brute-force protection for real-world applications like REST APIs and multi-tenant SaaS.
