Keycloak is the dominant open-source identity and access management server, providing single sign-on, social login, multi-factor authentication, and user federation for both workforce and customer identity. Born at Red Hat and now a CNCF project, it implements OpenID Connect and SAML and is the default self-hosted answer to Auth0-style products. It is entirely free to run, with commercial support available through Red Hat build of Keycloak. It suits teams that want full control of their identity stack without per-user pricing.
