We’re pleased to discuss a new aspect of social authentication in Django: adding Facebook authentication to your apps. We’re increasing the number of authentication methods available to customers to give them even more seamless sign-in experiences. This comes after we successfully implemented Google authentication using Django-Allauth and improved user engagement.
Social login features like Facebook authentication offer users convenient ways to access your web application without the hassle of managing additional credentials. In this post, we’ll guide you through setting up Facebook authentication with Django-Allauth. We’ll cover essential configurations, customization techniques, data management practices, testing strategies, and critical security considerations to ensure a seamless and secure integration.
If you’ve found value in our previous discussion on Google authentication, you’ll appreciate the insights and techniques shared in this guide for integrating Facebook authentication. Let’s continue our journey of empowering Django applications with versatile social authentication capabilities, focusing this time on seamlessly incorporating Facebook authentication into your project!
Check out our comprehensive guide on Django + Google Authentication: Elevate Your App’s Security With This Comprehensive Guide.
Initially, set up a new virtual environment, followed by creating a Django project and a Django App within it.
1.1 Create a virtual environment.
python3 -m venv env_social_login
1.2 Active virtual environment in Linux.
source env_social_login/bin/activate
1.3 To activate a virtual environment in Windows, run the below command.
env_social_login\Script\activate
1.4 Install Django within your virtual environment to encapsulate its dependencies and version, ensuring compatibility with your project.
pip install django
1.5 Create a new Django project using the following command.
django-admin startproject social_login
cd social_login/
1.6 Create a new App using the following command.
python manage.py startapp authapp
Install the all-auth package within your Django project’s virtual environment, and configure its settings as necessary to meet requirements.
2.1 Install the all-auth package within your virtual environment by executing the following installation command.
pip install django-allauth
pip install django-allauth[socialaccount]
2.2 Configure the settings for all-auth according to your project’s requirements, ensuring proper integration and functionality within your Django application.
settings.py file of your social_login project:
import os
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
'django.template.context_processors.request',
],
},
},
]
AUTHENTICATION_BACKENDS = [
# Needed to login by username in Django admin, regardless of `allauth`
'django.contrib.auth.backends.ModelBackend',
# `allauth` specific authentication methods, such as login by email
'allauth.account.auth_backends.AuthenticationBackend',
]
INSTALLED_APPS list within the settings.py file of your project:
'authapp',
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.facebook', # for facebook login
MIDDLEWARE list within the settings.py file of your project:
'allauth.account.middleware.AccountMiddleware',
urls.py file of your project:
from django.urls import path, include
path('accounts/', include('allauth.urls')),
python manage.py migrate
python manage.py createsuperuser
python manage.py runserver
Select the “Other” option for your app and click on the “Next” button.
Select the “consumer” option for your app and click on the “Next” button.
Provide “Add an app name” and “App Contact Email”, and hit the “Create App” button. You’ll have to go through a security check to create an app.
Select “Set Up” of “Facebook Login” Product.
Then, Go to the “App settings” and select “Basic”.
Add the below requirement in the open from:
Now store the App ID and App Secret and click on “Save Changes”.
If you want to enable authenticated user login via Facebook on your website or server, follow these steps:
4.1 Include the following configuration in your settings.py file:
SOCIALACCOUNT_PROVIDERS = {
'facebook': {
'APP': {
'client_id':<your_app_id>,
'secret': <your_app_secret>
},
'METHOD': 'oauth2', # Set to 'js_sdk' to use the Facebook connect SDK
'SDK_URL': '//connect.facebook.net/{locale}/sdk.js',
'SCOPE': ['email', 'public_profile'],
'AUTH_PARAMS': {'auth_type': 'reauthenticate'},
'INIT_PARAMS': {'cookie': True},
'FIELDS': [
'id',
'first_name',
'last_name',
'middle_name',
'name',
'name_format',
'picture',
'short_name',
],
'EXCHANGE_TOKEN': True,
'VERIFIED_EMAIL': False,
'VERSION': 'v17.0',
'GRAPH_API_URL': 'https://graph.facebook.com/v17.0',
}
}
LOGIN_URL = 'login'
LOGOUT_URL = 'logout'
LOGIN_REDIRECT_URL = 'dashboard'
LOGOUT_REDIRECT_URL = 'login'
SOCIALACCOUNT_AUTO_SIGNUP = True
SOCIALACCOUNT_LOGIN_ON_GET = True
4.2 Add the following code snippet to the views.py file of your Django app:
from django.shortcuts import render, redirect
# Create your views here.
from django.contrib.auth.decorators import login_required
from django.contrib.auth import logout
# Create your views here.
def userLogin(request):
return render(request,'login.html')
@login_required
def dashboard(request):
print(request)
return render(request,'dashboard.html')
def userlogout(request):
# Logout the user
logout(request)
return redirect('login')
4.3 Create a urls.py file in your authapp and add the following code:
from django.urls import path
from .views import userLogin, dashboard, userlogout
urlpatterns = [
path('', userLogin, name='login'),
path('dashboard/', dashboard, name='dashboard'),
path('logout/', userlogout, name='logout'),
]
4.4 Add the following code snippet to the urls.py file of your project:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('authapp.urls')),
path('accounts/', include('allauth.urls')),
]
4.5 Create a “templates” folder at the project level of your Django project, and then add the login.html and dashboard.html templates into this folder.
login.html
