# Authentication

> Create, store, and send a Galileo API key.

Create an API key in the [Playground](https://playground.physionlabs.ai/api-keys). Store it in `GALILEO_API_KEY` on your server.

```bash theme={null}
export GALILEO_API_KEY="gk_live_..."
```

Both SDKs read this variable automatically. You can also pass the key when constructing a client.

    ```python theme={null}
    galileo = Galileo(api_key=os.environ["GALILEO_API_KEY"])

Keep API keys out of browser code, mobile applications, source control, and logs. Call Galileo from a server you control.

`GET /v1/status` accepts requests without a key. For upload PUT requests, use the temporary upload URL and omit the Galileo API key.
