Definition
Authentication in Django is the process of verifying who a user is (e.g., through login and session management). It is part of Django’s built-in django.contrib.auth system.
Why It Matters
Security is non-negotiable in modern web applications. Django’s authentication system provides a battle-tested, secure way to manage user identities, protecting both user data and application integrity from unauthorized access.
Core Concepts
- Users: The central object of the auth system.
- Login/Logout: Views that handle the session lifecycle.
- Password Hashing: Django never stores passwords in plain text.

user = authenticate(username='alice', password='password123')
if user is not None:
