Casdoor is an open-source, UI-first Identity and Access Management (IAM) and Single Sign-On (SSO) platform that provides a web-based admin console for managing users, organizations, and authentication flows. It is designed to integrate with applications via standard identity protocols and offers extensible user authentication options.
Key Features
- Web UI for user, organization, application and permission management
- SSO and federation support via OAuth 2.0, OpenID Connect (OIDC), and SAML 2.0
- Directory and provisioning integrations including LDAP and SCIM
- Multiple authentication methods including WebAuthn and TOTP-based MFA
- Built-in registration, email verification, and password recovery flows
- Public REST API and SDKs to simplify application integration
Use Cases
- Centralized login and SSO for internal apps and SaaS-style multi-tenant products
- Adding MFA and modern authentication (OIDC/WebAuthn) to existing services
- User lifecycle management and provisioning across connected systems
Casdoor fits teams that want an admin-friendly IAM/SSO solution with broad protocol support and a ready-to-use web console. It is especially useful when you need standards-based SSO plus flexible authentication methods in one deployable service.
