Creating a User Registration Form in Django

User authentication is one of the most fundamental features in any web application. Whether you are building a blog, an e-commerce platform, or a social media site, allowing users to create accounts and log in securely is essential. Django, being a high-level Python web framework, provides powerful built-in tools to handle authentication, registration, and user management with minimal effort.

In this post, we will go through the complete process of creating a user registration form using Django’s built-in User model and form handling system. We will discuss how to design the form, validate user input, securely store passwords, and integrate everything into Django views and templates.

By the end of this post, you will understand not only the code but also the reasoning behind each step. Let’s dive in.

1. Introduction to Django Authentication System

Django comes with a robust authentication framework that handles everything from login, logout, password hashing, session management, and even group permissions. Instead of reinventing the wheel, developers can leverage Django’s built-in tools to quickly build secure user systems.

The authentication system revolves around the User model, which stores information such as username, email, password, and more. Django also provides forms and utilities to authenticate and manage users easily.

For our project, we’ll focus on user registration — allowing new users to create accounts.

2. Understanding the Built-in User Model

Before we start coding, let’s understand the Django User model. It resides in the module django.contrib.auth.models and contains the following fields by default:

• username: The unique identifier for a user.
• email: The user’s email address (optional by default).
• password: The user’s password (stored as a hash, not plain text).
• first_name and last_name: Optional personal name fields.
• is_staff, is_active, and is_superuser: Boolean flags to control user permissions.
• date_joined and last_login: Timestamps for user activity.

You can either use this model directly or extend it if you need extra fields like phone number or profile picture. For now, we’ll use it as-is to keep things simple.

3. Setting Up the Django Project

Let’s start by creating a Django project and an app for our registration system.
