Yet Another Implementation of OTP for Django

What This?

This script is "Yet Another Implementation" of 2 factor authentication.

Why I re-invent?

First, I tried Django OTP, but 2 FA code is required though it should be optional. Moreover, Admin Panel to edit/fix secret key is not provided.

Then, I tried django-two-factor-auth, but I found it is the wrapper of Django OTP that requires 2FA code to the user who doesn't have 2FA enabled.

How to use

1. Install this script. There's pip package and you can install it by pip install django_good_otp.
2. Create a Django project as usual.
3. Edit settings.py. You will need to edit INSTALLED_APPS and AUTHENTICATION_BACKENDS. For detail, refer Edit Settings section.
4. Run migration as usual.
5. Edit url.py of your root URL config to enable QR Code. For details, Check out URL Routing section.
6. To enable admin panel, you will need to write very small code. For details, Check out Enable Admin Panel section.
7. To use 2FA on Admin panel login, you will also need to write very simple code. For details, Check out Enable Admin Panel section.

Edit settings

You will need to edit configuration such settings.py. The variable to edit is INSTALLED_APPS and AUTHENTICATION_BACKENDS.

INSTALLED_APPS

You will just need to add 'django_otp.DjangoOTP' after 'django.contrib.auth' i.e. it should be like this:

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    "django_otp.DjangoOTP"
]

Note that this depends on the case. i.e. If you have more apps installed/uninstalled, your INSTALLED_APPS list might be longer/shorter than this.

AUTHENTICATION_BACKENDS

To use 2 FA, you will need to replace authentication backend with the backend this module provides. i.e. just set AUTHENTICATION_BACKENDS in settings.py to ("django_otp.backends.OTPAuthBackend", ). i.e. like this:

settings.py

AUTHENTICATION_BACKENDS = ("django_otp.backends.OTPAuthBackend", )

URL Routing

This module supports QRCode to transfer Secret Key to your device. To use it, you will need to add django_otp.urls with include function like this:

urls.py

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^qr/', include("django_otp.urls"))
]

Enable Admin Panel

Admin Panel

By default, Admin Panel of the model that stores secret key is disabled. To enable Admin Panel, you will need to call OTPAdmin.enable() method like this:

urls.py

from django.conf.urls import url, include
from django.contrib import admin
from django_otp.admin import OTPAdmin

OTPAdmin.enable()

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^qr/', include("django_otp.urls"))
]

Using 2FA form on adminsite

Unfortunately, login template of administration site doesn't handle custom login form. Therefore, to use 2FA-ready admin form, you will need to replace admin.site with django_otp.admin.AdminSite. i.e. like this:

urls.py

from django.conf.urls import url, include
from django.contrib import admin

from django_otp.admin import AdminSite

OTPAdmin.enable()
admin.site = AdminSite()

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^qr/', include("django_otp.urls"))
]
