# Component Access Control

The `access` attribute on the `aura:component` tag controls whether the component can be used outside of the component’s namespace.

Possible values are listed below.

| Modifier | Description                                                       |
| -------- | ----------------------------------------------------------------- |
| `public` | Available within your org only. This is the default access value. |
| `global` | Available in all orgs.                                            |

:::note
Components aren’t directly addressable via a URL. To check your component output, embed your component in a `.app` resource.
