django-scatter-auth is a pluggable Django app that enables login/signup via Scatter (EOS extension wallet). The user authenticates themselves by digitally signing the hostname with their wallet's private key.

Quickstart

----------

Install django-scatter-auth with pip::



    pip install django-scatter-auth



Add it to your `INSTALLED_APPS`:



.. code-block:: python



    INSTALLED_APPS = (

        ...

        'scatterauth.apps.scatterauthConfig',

        ...

    )



Set `'scatterauth.backend.ScatterAuthBackend'` as your authentication backend:



.. code-block:: python



    AUTHENTICATION_BACKENDS = [

    'django.contrib.auth.backends.ModelBackend',

    'scatterauth.backend.ScatterAuthBackend'

    ]



Set your User model's field to use as public key storage:



.. code-block:: python



    SCATTERAUTH_USER_PUBKEY_FIELD = 'username'



And if you have some other fields you want to be in the SignupForm, add them too:



.. code-block:: python



    SCATTERAUTH_USER_SIGNUP_FIELDS = ['email',]



Add django-scatter-auth's URL patterns:



.. code-block:: python



    from scatterauth import urls as scatterauth_urls



    urlpatterns = [

        ...

        url(r'^', include(scatterauth_urls)),

        ...

    ]



Add some javascript to handle login:



.. code-block:: html



    



.. code-block:: javascript



    var login_url = '{% url 'scatterauth_login_api' %}';

    document.addEventListener('scatterLoaded', scatterExtension => {

      console.log('scatter loaded');

      if (scatter.identity) {

        console.log("Identity found");

        loginWithAuthenticate(login_url,console.log,console.log,console.log,console.log, function (resp) {

          window.location.replace(resp.redirect_url);

        });

      } else {

        console.log('identity not found, have to signup');

      }

    });



You can access signup using {% url 'scatterauth_signup' %} and API signup using {% url 'scatterauth_signup_api' %}.

Important details and FAQ

-------------------------



1. *If you set a custom public key field (SCATTERAUTH_USER_PUBKEY_FIELD), it MUST be unique (unique=True).*



This is needed because if it's not, the user can register a new account with the same public key as the other one,

meaning that the user can now login as any of those accounts (sometimes being the wrong one).



2. *How do i deal with user passwords or Password is not set*



There should be some code in your project that generates a password using ``User.objects.make_random_password`` and sends it to a user email.

Or, even better, sends them a 'restore password' link.

Also, it's possible to copy signup_view to your project, assign it a url, and add the corresponding lines to set some password for a user.



3. *Why don't i have to sign a message? It's needed in django-web3-auth, how this app is secure?*



This app uses scatter's ``authenticate`` function to handle message signing - hostname being the signed message.

This means that the user & the client share knowledge of the original message and the server can verify

client's possession of the private key corresponding to the public key.



Running Tests

-------------



Does the code actually work?



::



    source /bin/activate

    (myenv) $ pip install tox

    (myenv) $ tox
