Django Tutorial Part 3: User Login, Logout & Registration (2025 Beginner Guide)

In Part 2, you learned how to create forms and accept user input. Now it’s time to handle user authentication. In this post, you'll add login, logout, and registration functionality using Django’s built-in auth system.

What You’ll Learn

Enable Django’s auth system
Create user registration (sign up) form
Add login and logout functionality
Secure pages to logged-in users only

Step 1: Configure URLs

Django provides built-in views for login and logout. First, update myproject/urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('myapp.urls')),
    path('accounts/', include('django.contrib.auth.urls')),  # Login/Logout
]

Step 2: Create Registration View

Create a view in myapp/views.py:

from django.contrib.auth.forms import UserCreationForm
from django.shortcuts import render, redirect

def register(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('login')  # Redirect to login after signup
    else:
        form = UserCreationForm()
    return render(request, 'registration/register.html', {'form': form})

Step 3: Create Registration Template

Create templates/registration/register.html:

<h2>Sign Up</h2>

<form method="POST">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Register</button>
</form>

Step 4: Add Registration URL

In myapp/urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
    path('create/', views.create_post, name='create_post'),
    path('register/', views.register, name='register'),
]

Step 5: Create Login & Logout Templates

Create templates/registration/login.html:

<h2>Login</h2>

<form method="POST">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Login</button>
</form>

<p>Don't have an account? <a href="{% url 'register' %}">Sign up</a></p>

Django automatically logs out users at /accounts/logout/. You can create a basic logout confirmation template at templates/registration/logged_out.html:

<h2>You have been logged out.</h2>
<a href="{% url 'login' %}">Log in again</a>

Step 6: Secure Views with Login Required

To restrict access to views, use the login_required decorator:

from django.contrib.auth.decorators import login_required

@login_required
def create_post(request):
    ...

Step 7: Redirect After Login

In myproject/settings.py add:

LOGIN_REDIRECT_URL = '/'
LOGOUT_REDIRECT_URL = '/accounts/login/'

Conclusion

You've successfully added user authentication to your Django app, including login, logout, and user registration. With authentication in place, you can now build dashboards, user-specific features, and protected content. Coming Next in Part 4: Learn how to add user profiles and permissions!
