LnAuth Django

This is a reusable Django application providing Lightning Network url authentication functionality.

Currently only login and register actions are supported.

Installation

You can install LnAuth-Django using pip:

pip install lnauth-django

Or, if you're using pipenv:

pipenv install lnauth-django

Configuration

Once installed, add 'lnauth_django' to your INSTALLED_APPS setting:

INSTALLED_APPS = [
    ...
    'lnauth_django',
    ...
]

Then, include the URL configuration in your project's urls:

from django.urls import include, path

urlpatterns = [
    ...
    path('lnauth_django/', include('lnauth_django.urls')),
    ...
]

Settings

Here are the settings you can set in your settings.py to customize Django My App:

• LNURL_AUTH_ROOT_DOMAIN: This is used to specify the domain for your app. By default, it should be the domain where your Django project is hosted. Required.

• LNURL_AUTH_K1_TIMEOUT: This is used to specify the timeout of the k1 challenge in seconds. By default, it is set to 60 * 60 seconds (1 hour).

• LNURL_AUTH_REGISTER_CALLBACK and LNURL_AUTH_LOGIN_CALLBACK: This is used to specify the import path of the callback function to be executed after user registration / login. Both are optional.

  LNURL_AUTH_REGISTER_CALLBACK = 'myapp.users.ln_auth.register_callback'
  

• LNURL_AUTH_BACKEND: This is used to specify the authentication backend that the library should use for login. Only needed if you're using multiple authentication backends.

• LNURL_AUTH_LOGIN_AFTER_REGISTER: Specify whether to automatically log in the user after registration. Default is True.

Usage

This app exposes two endpoints:

• /ln-auth-get-url: Generate a LNURL to be used for authentication. Takes a query parameter called action which can be set to login or register.

• /ln-auth: Which is called by the authenticating wallet. Takes all the parameters as specificed in the LNURL Auth spec.

Both will reject authenticated requests.

Any kind of frontend is out of scope for this library, but the intended approach is to render the link returned by /ln-auth-get-url as a QR code and allow the user to use their preferred lightning wallet to log in.
