Authorizer
Authorizer is an open-source identity provider that functions as a centralized authentication and authorization platform. It manages user identities and session lifecycles by implementing standard OpenID Connect protocols, allowing for secure verification across web, mobile, and backend applications. The service is designed as a containerized microservice that provides a unified interface for administrative and authentication operations.
The platform distinguishes itself through a multi-tenant architecture that isolates authentication rules and user data across different business domains. It incorporates a policy-based access engine to enforce fine-grained permissions and role-based access control, while supporting machine-to-machine authentication through scoped token issuance. Developers can interact with the service via GraphQL, REST, or gRPC, and integrate authentication flows directly into their applications using provided client-side tools.
Beyond core identity management, the system includes comprehensive security features such as multi-factor authentication, external identity federation, and automated threat protection. It maintains a database-agnostic persistence layer and offers event-driven automation through a webhook system that triggers external workflows based on authentication actions. Operational visibility is supported through audit log streaming, performance metrics, and standardized discovery metadata for automated client configuration.
