AuthEngine is an open-source identity and access management (IAM) platform. It gives your applications a single place to handle sign-in, multi-tenant access control, OIDC federation, and audit — so you stop rebuilding login in every service.
People sign in once. Your APIs, dashboards, and partner apps all trust the same identity: who the user is, which organization they belong to, and what they are allowed to do.
AuthEngine is built for teams that run more than one application or more than one customer organization and need authentication, permissions, and policy to stay consistent across the stack.
- Single sign-on — one login across all your apps and APIs
- Multi-tenant — organizations, roles, and permissions built in, not bolted on
- OIDC federation — connect external identity providers or act as one yourself
- Audit trail — every security-relevant action is logged
AuthEngine provides a production-ready backend, an admin dashboard, and infrastructure tooling for deployment on AWS EC2 with K3s, Rancher, and Helm (in-cluster databases). Local development uses Docker Compose.
