Multi-Product SSO Authentication Platform

Overview

Single sign-on authentication infrastructure integrating multiple applications

Details

Designed and developed an integrated authentication platform from scratch for a client with multiple SaaS products. Built an OAuth2.0/OpenID Connect compliant SSO system that improves user experience while strengthening security. Implemented external IdP integration (Google Workspace, Azure AD, etc.) via SAML/OIDC, multi-factor authentication (MFA), organization/role-based access control, and detailed audit logging. Redis-based session management ensures fast response times. Anticipating deployment to security-sensitive financial services, we adopted OWASP-compliant security design. We support stable operations through continuous vulnerability assessments and improvements.
