Google is releasing a new Search Console feature called associations. This feature will allow you to connect your account with your other Google properties, such as YouTube.
Search Console will now be able to connect with Google Analytics, Google Ads, YouTube, Play Console, Actions Console and Chrome Web Store. The Google Analytics association will allow you to view Search Console data in Analytics, such as organic search queries. You will also get better coverage of your organic search results because your domain properties will be linked to Analytics. Essentially giving you a more complete picture.
You have previously been able to make associations with Search Console. In this case they will be carried over to the new Associations page. These new associations, as stated by Google, will unlock more functionality for your site.
