# Authentication

> Authenticate with the Notte SDK

The SDK handles authentication automatically using your API key.

## Get your API key

1. Sign in to the [Notte Console](https://console.notte.cc)
2. Navigate to your account settings
3. Generate or copy your API key

## Environment variable (recommended)

Set the `NOTTE_API_KEY` environment variable:

```bash theme={null}
export NOTTE_API_KEY=your_api_key_here
```

Then initialize the client:

```python theme={null}
from notte_sdk import NotteClient

client = NotteClient()
```

## Direct initialization

Pass the API key directly:

```python theme={null}
from notte_sdk import NotteClient

client = NotteClient(api_key="your_api_key_here")
```
