# Auth Controller

> Auth Controller

The Authentication API provides endpoints for user authentication, token generation, and user session management within the Sign Station platform. This API handles both user login (username/password) and OAuth2 client authentication flows. The `/auth/login` and `/auth/token` endpoints do not require authentication (they generate tokens). The `/auth/me` endpoint requires a valid JWT Bearer token obtained from login or token endpoint. **Token Generation:** Use `/auth/login` for user tokens or `/auth/token` for OAuth2 client tokens. For dashboard sign-in, see [Logging In](https://knowledge.leegality.com/sign-station/getting-started/logging-in); to generate OAuth2 client credentials from the dashboard, see [API Credentials](https://knowledge.leegality.com/sign-station/api-credentials).
