# Interface Access Control

The `access` attribute on the `aura:interface` tag controls whether the interface can be used outside of the interface’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.|

A component can implement an interface using the `implements` attribute on the `aura:component` tag.
