Streamlit is an open-source Python framework that allows data scientists and machine learning engineers to create interactive web applications from existing Python scripts, offering a user-friendly alternative for those with limited CSS skills. Previously, integrating authentication and authorization features into Streamlit apps was limited, but the recent integration with PropelAuth enhances these capabilities by using OpenID Connect (OIDC) support to streamline the process. This integration simplifies the implementation of PropelAuth's features such as role-based access control (RBAC), organizational management, and multiple login methods, making it easier for developers to protect resources based on user roles and permissions within an organization. The integration process now requires only a few lines of code, significantly improving ease of use and security for Streamlit applications.
