Hardened, operator-free self-hosted SSO/identity stack: Keycloak (OIDC/SAML identity provider) + PostgreSQL (Keycloak's database) + oauth2-proxy (an auth proxy you place in front of any upstream app to authenticate users against Keycloak), wired together so you get single sign-on in front of your apps out of the box.
