 By default, Stream embed codes can be used on any domain. If needed, you can limit the domains a video can be embedded on from the Stream dashboard.
 
 In the dashboard, you will see a text box by each video labeled `Enter allowed origin domains separated by commas`. If you click on it, you can list the domains that the Stream embed code should be able to be used on.

+### Allowed Origins
+
+The Allowed Origins feature lets you specify which origins are allowed for playback. This feature works even if you are using your own video player. When using your own video player, Allowed Origins restricts which domain the HLS/DASH manifests and the video segments can be requested from.

 ### Signed URLs
 
 Combining signed URLs with embedding restrictions allows you to strongly control how your videos are viewed. This lets you serve only trusted users while preventing the signed URL from being hosted on an unknown site.
