In this session, we will explain how we standardized and streamlined authentication flows to address the growing workload faced by engineers due to the rapid increase in authentication services.

To tackle the challenging task of building individual authentication flows for over 100 services, we adopted an implementation approach that defines authorization levels using role information and leverages attribute data stored in Keycloak.

By accurately linking user information with imported role data and standardizing authentication flows, we enabled faster updates to authorization systems. Additionally, we implemented centralized policy management for each client using OPA (Open Policy Agent) and policy language, significantly improving maintenance efficiency.

This session will provide practical and scalable design strategies and implementation methods for building robust systems that address au
