Current browsers (especially Safari and Chome in ingognito mode) are now blocking 3rd party cookies and when you embed videosync player to your website, videosync cookies are treated as 3rd party cookies.

We use cookies in Videosync for authentication and registration features to identify whether the user is already authenticated or registered. If your video has authentication or registration enabled, it means that the browsers blocking 3rd party cookies won't remember user's session. By default Videosync lets user to insert the password or register, but if viewer refreshes the page the viewer will need to auth/register again.

We have built optional workaround to preserve the session even in the browsers blocking the cookies. It stores the session to parent page's (your page) localstorage and to enable it you will need to add this script to the page(s) you are embedding videos.

<script type="text/javascript" src="//"></script>
