# Asset Origin

Your default Library storage is defined in the **Library > Storage** configuration page.\
However, you can optionally configure external storage providers as Origin sources for your assets. Once configured, these external storage providers will be hidden behind an alias within your dynamically optimized URLs.

{% hint style="info" %}
The **Alias** makes it easier to manage links across platforms or to hide complex paths.
{% endhint %}
