Recently during a company hackathon we decided to try out using oso's Polar language for a different kind of use case – making a game!

Using Azure Active Directory's B2C identity platform and oso's open-source authorization library for Flask, we'll show how to add user authentication and access control to a simple Flask app.

In this post, we'll show how to incrementally build complex authorization policies with oso, using GitHub's authorization model as an example.
