# API key

To use the API key, you can either:

* **Set the API key as the `E2B_API_KEY` environment variable** to avoid passing it each time you create a sandbox.
* Or pass it directly to the `Sandbox` constructor as shown below:

<CodeGroup>
  ```js JavaScript & TypeScript theme={"theme":{"light":"github-light","dark":"github-dark-default"}}
  import { Sandbox } from 'e2b'

  const sandbox = await Sandbox.create({ apiKey: 'YOUR_API_KEY' })
  ```

  ```python Python theme={"theme":{"light":"github-light","dark":"github-dark-default"}}
  from e2b import Sandbox

  sbx = Sandbox.create(api_key="YOUR_API_KEY")
  ```
</CodeGroup>

# Access token

<Warning>
  `E2B_ACCESS_TOKEN` is deprecated. New access tokens can no longer be generated after **July 1, 2026**, and all access tokens stop working on **August 1, 2026**. Authenticate with `E2B_API_KEY` instead. See the [access token deprecation](/docs/migration/access-token-deprecation).
</Warning>

The access token is used only by the interactive CLI login commands `e2b auth login` and `e2b auth configure`, which set up your local workstation. It is **not needed in the SDK**, and you do not need to set it as an environment variable to use the CLI.

## Where to find access token

You can get your **Access token key** at the [dashboard](https://e2b.dev/dashboard/account). After July 1, 2026, new access tokens can no longer be generated.
