Do Google publish details of how they will further rollout 3rd party cookie restriction beyond the 1%

[Dory998]

Concern I have is that pocket of my customer/user population will find their browsers change one day and features stop working before we've tested them. Is it a case of a gradual ramp up from 1 to 100%?
As of January 4, 2024, Google has started restricting third-party cookies by default for 1% of Chrome browsers. This change is part of their plan to facilitate testing and gradually ramp up to 100% of users by the third quarter of 2024.

Hi @Dory998 — thanks for your question.

The timeline for third-party cookie phaseout in Chrome has been updated.

privacysandbox.com/open-web shows the current timeline.

The 1% testing period continues through the second half of 2024. Subject to resolving any competition concerns, Chrome plans to begin rolling out third-party cookie phaseout to all Chrome clients starting from early 2025.

Users in the 1% group can temporarily allow third-party cookies for a site by clicking the eye icon in Chrome's address bar.

@samdutton thanks for the info sam. am I right in thinking the 1% will remain as this and no further populations will be added to? thanks
