Identity engineering beyond the happy path

Practical guides to Keycloak, OAuth 2.0, OpenID Connect and identity federation: how the protocols behave on the wire, which settings matter, and what breaks in production. Most posts come with a lab you can run, so you can decode the tokens yourself.

Hi, I’m Filip, an IAM engineer in Vienna with 15+ years in software. Today I work on Keycloak at a large European retailer: OIDC and SAML clients, Entra ID brokering, and highly available clusters on Kubernetes in the cloud.
