Django AllAuth MFA Setup Fix

In this tutorial, you'll learn about Django AllAuth MFA Setup Fix. We cover key concepts, practical examples, and best practices.

The Problem

Password-only authentication is vulnerable to credential theft. Without MFA, a leaked password gives attackers full account access. Allauth supports TOTP but needs explicit configuration.

Quick Fix

Wrong — no MFA, password only

# settings.py
# MFA not configured — password is the only factor

Output: Compromised password means compromised account. No second factor.

Correct — enable TOTP MFA

# settings.py
INSTALLED_APPS = [
    'allauth.mfa',
    ...
]

# Require MFA for all users
ACCOUNT_LOGIN_METHODS = {'email'}
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'
MFA_ENABLED = True
MFA_TOTP_ISSUER = 'DodaTech'

URL configuration

# urls.py
urlpatterns = [
    path('accounts/', include('allauth.urls')),
    # MFA URLs are included automatically
]

Enforcing MFA per user type

# adapters.py
from allauth.account.adapter import DefaultAccountAdapter

class CustomAccountAdapter(DefaultAccountAdapter):
    def is_mfa_required(self, request, user):
        if user.is_staff or user.is_superuser:
            return True
        return False

# settings.py
ACCOUNT_ADAPTER = 'myapp.adapters.CustomAccountAdapter'

Customizing MFA templates

# Templates/account/mfa/authenticate.html
"""
{% extends "account/base.html" %}
{% block content %}
<h2>Two-Factor Authentication</h2>
<p>Enter the code from your authenticator app.</p>
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Verify</button>
</form>
{% endblock %}
"""

Recovery codes

# Allauth generates recovery codes during MFA setup
# Users should download or print them

# Access recovery codes in the UI
# /accounts/mfa/ — management page with recovery codes

Prevention

• Enable MFA for all staff/admin accounts.
• Use is_mfa_required() to enforce policies per user role.
• Test MFA with Google Authenticator or Authy during development.

Common Mistakes with allauth mfa setup

1. Placing the wildcard pattern first in case expressions, making all subsequent patterns unreachable
2. Using head and tail instead of pattern matching, causing runtime errors on empty lists
3. Forgetting that lazy evaluation defers computation until the value is forced, causing space leaks with unevaluated thunks

These mistakes appear frequently in real-world DJANGO code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
