# Authentication

> Authentication is handled via API keys. You can find and manage your keys in your Argus Dashboard.

### Runtime Security Key

This key is designed for production applications and is required to unlock the full suite of Argus Platform features. Use this key to connect your application to policies managed in the UI, organize data with assets, track conversations with sessions, and save all scan results for in-depth analytics.

### Best Practice: Environment Variables

To keep your keys secure and avoid hardcoding them in your source code, it is strongly recommended to use environment variables.

```bash theme={null}
# Set the variable in your shell
export ARGUS_API_KEY="your_api_key_here"
```

The SDK can then be initialized by reading the key from the environment.
