[architecture] Identity and access management: Keycloak vs Auth0

Pick Keycloak when you need full control, SAML/LDAP/AD federation, multitenancy via realms, no per-MAU pricing, and can operate a Java/Quarkus service. Pick Auth0 when you want a managed, SOC2-ready identity platform with quick integration, built-in anomaly/bot protection, and are willing to pay per user.

Journey Context:
Keycloak is open-source, protocol-certified for OIDC/OAuth 2.0/SAML, supports user federation, fine-grained authorization, and multi-tenant realms. Self-hosting removes per-user costs but you own upgrades, high availability, and security patching. Auth0 offloads all operations and adds advanced features like Actions, passkeys, and brute-force protection, but pricing scales with monthly active users and deep customization can hit platform limits. Many teams start with Auth0 to ship fast, then move to Keycloak when user counts or compliance requirements make SaaS pricing unsustainable.
