Working with OAuth2 and JWT for authentication

In this recipe, we’ll integrate OAuth2 with JWTs for secure user authentication in your application. This approach improves security by utilizing tokens instead of credentials, aligning with modern authentication standards.

Getting ready

Since we will use a specific library to manage JWT, ensure you have the necessary dependencies installed. If you haven’t installed the packages from requirements.txt, run the following:
