Use the `crossOrigin` option to add a [`crossOrigin` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/crossorigin) in all `<script>` tags generated by the <AppOnly>[`next/script`](/docs/app/guides/scripts) component</AppOnly> <PagesOnly>[`next/script`](/docs/pages/guides/scripts) and [`next/head`](/docs/pages/api-reference/components/head)components</PagesOnly>, and define how cross-origin requests should be handled.

```js filename="next.config.js"
module.exports = {
  crossOrigin: 'anonymous',
}
```
