Securing your Flask application using Kratos and Keto

In this detailed exploration of user authentication and access control in Python using Flask, the author demonstrates how to integrate Ory Kratos and Ory Keto for managing user identities and permissions efficiently. The setup involves using Flask Cookiecutter to structure projects and Docker alongside Docker Compose to manage containers for running Postgres services, which serve as databases for Ory Kratos and Keto. Ory Kratos is responsible for user authentication, storing identity data like email and passwords, while Ory Keto handles access control by managing permissions for different resources within the application. The article emphasizes the importance of using command-line tools for handling permissions, despite the lack of a user interface, and highlights the benefits of automating these processes through CI/CD pipelines. Additionally, the author suggests using SDKs for Ory Kratos and Keto to enhance code readability and advises on future improvements, such as adding two-factor authentication, social sign-in features, and more robust password policies. The complete code for the project is available on GitHub, providing a practical resource for developers looking to implement similar authentication and access control systems.
