You are using Vimeo to stream your content and you have Vimeo Premium account, then you have the following option to restrict the access to your content.
High-level setup available at the live event creation level of Vimeo
Public : accessible to anyone
Only me : your login/password of vimeo will be required to access the content
People I follow : only the people you follow on Vimeo can see this video, and it will appear in their feeds.
Password : will allow you to add a password for viewers to gain access to your video, including Vimeo and non-Vimeo members.
Private link : is a semi-private setting that will make your individual video visible only to people who have the link. Your video’s credits will be removed, and the video will be removed from any channels or groups. Please note that anyone with access to this link can share it with anyone else.
Hide from Vimeo : will make the video unable to be accessed on the Vimeo website (unless you are logged in as yourself), but it still can be embedded on other websites. Your video can be added to showcases and portfolios, but no other types of collections.
Specific domains : Paid users also have access to domain-level privacy, which means that you can choose what specific website you want to allow your video to be embedded on. In the example below, only users coming from stxus.pp-shop.secutix.com will be able to see your content.
