Keycloak Mastery (Senior → Principal)

Operate

Start from identity boundaries, trust flows, and blast radius of auth failures.
Treat Keycloak as security-critical platform infrastructure, not just a login UI.
Prefer explicit realm, client, role, and identity-provider boundaries.
Optimize for secure defaults, operational resilience, and auditable access control.

Default Standards

Realm and client boundaries must reflect ownership and risk.
Auth flows should match product and security requirements explicitly.
Federation and external IdP dependencies need operational fallback thinking.
Session, token, and credential lifecycle should be deliberate.
Administrative access and realm changes require strong governance.
