I pay for Youtube Premium, which uses third-party cookies to not show ads on embedded videos.

https://privacysandbox.com talks about advertising, but not "logged in elsewhere" functionality. Does Youtube or Google have something ready, or will all Youtube Premium subscribers see ads on embedded videos?

There is also a Federated Credential Management (FedCN) API coming in, that should help somewhat.

Thank you! Will look!

> Youtube Premium, which uses third-party cookies to not show ads on embedded videos

The third party cookies don't control ads in embedded videos, there are currently no ads in embedded videos whether you have paid for premium or not.

I have a bookmarklet that converts a youtube page to an embed for this reason, for when I get sick of seeing the same couple of adverts on a loop.

I see ads in YouTube embeds all the time.

It's whitelisted based on the embedding domain.

>Ads appear on brand safe sites: YouTube works diligently so that our advertisers' brands appear on sites that reflect our respective core values. Our systems closely evaluate websites and their content against various factors when finding out whether to turn on In-stream ads on YouTube embeds. These factors include a strict set of guidelines on content like adult imagery, violence, inappropriate and hateful language, and sites that promote infringement.

The recommended solution for embedded content is the Storage Access API, which has broad browser support. (I don't know that YouTube has implemented it yet, but I'd be surprised if it's not there soon.)

The Storage Access API is an unmitigated pile of garbage. Google's page on it admits as much (https://developers.google.com/privacy-sandbox/3pcd/storage-a...).

From Google's own page: "Work is continuing to resolve all remaining blocking issues, before standardizing the API."

Perhaps they should switch to first party cookies?

How would that work on embedded videos on sites outside of YouTube/Google, which is what the parent comment is talking about?
