+## API Key Authentication
+
+llamactl now supports API Key authentication for both management and inference (OpenAI-compatible) endpoints. The are separate keys for management and inference APIs. Management keys grant full access; inference keys grant access to OpenAI-compatible endpoints
+
+**How to Use:**
+- Pass your API key in requests using one of:
+  - `Authorization: Bearer <key>` header
+  - `X-API-Key: <key>` header
+  - `api_key=<key>` query parameter
+
+**Auto-generated keys**: If no keys are set and authentication is required, a key will be generated and printed to the terminal at startup. For production, set your own keys in config or environment variables.
+
