Two-factor authentication (2FA) module in Django using the
Step 1: Install Required Packages Install the
django-two-factor-auth package, which provides 2FA functionality in Django. You can install it using pip:
pip install django-two-factor-auth
Step 2: Configure the Application In your Django project, open the
settings.py file and add the following configurations:
INSTALLED_APPS = [ # Other installed apps... 'django_otp', 'django_otp.plugins.otp_totp', 'two_factor', ] MIDDLEWARE = [ # Other middleware... 'two_factor.middleware.threadlocals.ThreadLocals', ] AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.ModelBackend', 'two_factor.auth_backends.OTPBackend', ] LOGIN_URL = 'two_factor:login' LOGIN_REDIRECT_URL = 'two_factor:profile' TWO_FACTOR_CALL_GATEWAY = 'two_factor.gateways.twilio.gateway.Twilio' TWO_FACTOR_TWILIO_ACCOUNT_SID = 'your_twilio_account_sid' TWO_FACTOR_TWILIO_AUTH_TOKEN = 'your_twilio_auth_token' TWO_FACTOR_PHONE_CALL_FROM = '+1234567890'
In this example, we configure the required settings for the
django-two-factor-auth package, including the installed apps, middleware, authentication backends, login URLs, and Twilio settings for phone call verification.
Step 3: Run Migrations Run the following command to apply the migrations for the
python manage.py migrate
Step 4: Enable 2FA for Users To enable 2FA for users, you can use the built-in
User model provided by Django. You can either create a custom user model or extend the existing
User model. Here’s an example:
from django.contrib.auth.models import AbstractUser from django_otp.models import SideChannelDevice class CustomUser(AbstractUser): otp_device = SideChannelDevice() class Meta: swappable = 'AUTH_USER_MODEL'
In this example, we create a custom user model called
CustomUser by extending the
AbstractUser model. The
otp_device field represents the OTP device associated with the user for 2FA.
Step 5: Protect Views with 2FA To protect views with 2FA, you can use the
@otp_required decorator provided by the
django-two-factor-auth package. Here’s an example:
from two_factor.decorators import otp_required @otp_required def my_view(request): # Your view logic here pass
In this example, the
@otp_required decorator is applied to the
my_view function-based view. It ensures that the user must authenticate using 2FA before accessing the view.
Step 6: Customize 2FA Templates The
django-two-factor-auth package provides default templates for the 2FA views. You can customize these templates by creating your own templates in your Django project’s
Please note that this is a basic example of a two-factor authentication module in Django using the
django-two-factor-auth package. You can further customize the module, such as using alternative 2FA methods, customizing the verification process, or implementing backup token functionality, based on your specific requirements.
