Identity is a critical part of modern application architecture, and many organizations are rethinking their reliance on cloud-based identity offerings. In this session, we’ll explore Keycloak: an open-source identity and access management platform. You’ll learn how it can be integrated into .NET applications to provide a powerful, flexible, and sovereign identity solution.

We’ll go beyond the basics of login and token validation. You’ll see how to customize Keycloak so it fits naturally into your application’s user experience, instead of feeling like a separate system bolted on the side. We’ll also look at modern authentication practices, including passkeys, and how they can improve both security and usability.

Using .NET Aspire, we’ll create a smooth local development experience that makes working with Keycloak practical and repeatable. Through demos, you’ll learn how to wire everything together, customize the authentication flow, and apply these concepts in your own solutions.
