Django Q & A


How to implement OAuth2 authentication in Django?

To implement OAuth2 authentication in a Django REST framework (DRF) API, you can leverage a package called `django-oauth-toolkit`. OAuth2 is a widely used protocol for securing APIs by allowing third-party applications to access user data without exposing user credentials. Here’s how you can set it up:


  1. Install `django-oauth-toolkit`:

   You can install it using pip:


   pip install django-oauth-toolkit



  1. Add `oauth2_provider` to your Django apps:

   In your project’s `` file, add `’oauth2_provider’` to the `INSTALLED_APPS` list.


  1. Migrate the Database:

   Run the following command to create the necessary database tables for `oauth2_provider`:


   python migrate



  1. Configure OAuth2 Settings:

   In your ``, configure the OAuth2 settings. For example:



       'SCOPES': {

           'read': 'Read scope',

           'write': 'Write scope',





  1. Create OAuth2 Applications:

   OAuth2 requires applications to be registered. You can create them using Django admin or programmatically. Each application will have a client ID and a client secret.


  1. Apply Authentication Classes:

   In your DRF views or viewsets, you can apply OAuth2 authentication classes like this:


   from oauth2_provider.contrib.rest_framework import OAuth2Authentication

   class YourApiView(APIView):

       authentication_classes = [OAuth2Authentication]

       permission_classes = [IsAuthenticated]



  1. Token Retrieval:

   Clients need to obtain access tokens by following the OAuth2 flow. This typically involves sending a POST request with client credentials and user authorization.


  1. Use Access Tokens:

   In your API views, you can now check for valid access tokens to secure your endpoints. The `IsAuthenticated` permission will handle this for you.


  1. Refresh Tokens (Optional):

   You can configure OAuth2 to issue refresh tokens, allowing clients to obtain new access tokens without user intervention.

OAuth2 is a powerful and flexible authentication mechanism for securing your Django REST API. By following these steps, you can implement OAuth2 authentication and provide secure access to your resources for third-party applications while keeping user credentials safe.
