# Login

`GET /login`

OAuth2 login endpoint. Initiates the OAuth2 authorization code flow.
    
    **Query Parameters:**
    - `redirect_uri`: The URI to redirect to after authentication (required)
    - `state`: A random string for CSRF protection (optional but recommended)
    
    **Flow:**
    1. Client redirects user to this endpoint with `redirect_uri` and `state`
    2. This endpoint redirects user to Auth0 for authentication
    3. After authentication, Auth0 redirects to `/callback` with authorization code
    4. `/callback` redirects back to the original `redirect_uri` with code and state
    
    **Example:**
    ```
    GET /login?redirect_uri=https://chat.openai.com&state=abc123
    ```
