* Handles user registration, login, password resets, etc.
* Issues tokens (JWT, session tokens, etc.) after successful authentication
* Examples: Auth0, Supabase Auth, Okta, or your own auth server
2. **LangGraph Backend** (Resource Server)
* Your LangGraph application that contains business logic and protected resources
2. **Agent Server** (Resource Server)
* Your agent or LangGraph application, which contains business logic and protected resources
* Validates tokens with the auth provider
* Enforces access control based on user identity and permissions
* Doesn't store user credentials directly
3. **Client Application** (Frontend)
* Web app, mobile app, or API client
* Collects time-sensitive user credentials and sends to auth provider
* Receives tokens from auth provider
* Includes these tokens in requests to LangGraph backend
* Includes these tokens in requests to the Agent Server

Here's how these components typically interact:
