PlatformCon 2025 – Scaling Secure Service Authentication with Keycloak’s Token Exchange

As platforms grow, secure authentication across services becomes complex:

• Frontend tokens are misused in backend services, leading to security risks
• Scattered API keys create operational and security challenges
• Microservices lack a standardized way to authenticate each other

In this talk at the PlatformCon 2025, I will demonstrate how Keycloak’s Token Exchange provides a scalable solution for modern platforms:

• Secure service-to-service authentication without exposing user tokens
• Dynamic external API authentication without managing static credentials
• Fine-grained token permissions to enforce least-privilege access

Attendees will gain practical implementation steps, real API examples, and best practices to build a scalable and secure authentication model using Keycloak.
