Google Chrome: Cookie deprecation starting in early 2025

May 31, 2024

Starting from January 4th, 2024, Chrome has restricted third-party cookies for 1% of its Stable users. This move is part of a broader strategy to test the effectiveness of Privacy Sandbox APIs, aimed at reducing cross-site tracking while maintaining the functionality necessary for free online content and services.

Key Changes and Timeline:

  • January 4th, 2024: third-party cookies restricted for 1% of Chrome Stable clients.
  • Early 2025: planned ramp-up to 100% third-party cookie restriction for all Chrome clients, contingent on resolving competition concerns raised by the UK's Competition and Markets Authority (CMA).
  • Ongoing: 20% of users on Chrome Canary, Dev, and Beta channels have third-party cookies restricted.

Privacy Sandbox Goals

The Privacy Sandbox initiative focuses on balancing user privacy with the need for functional online services. Third-party cookies have been instrumental in providing features like sign-in, fraud protection, and advertising, but they also enable cross-site tracking. Chrome's approach involves developing a range of privacy-focused APIs to replace the functionality of third-party cookies without compromising user privacy.

Impact on Users and Developers

From early 2024, a growing number of Chrome users will experience the web without third-party cookies, even if their sites are not part of the Chrome-facilitated testing. This transition period allows developers to adapt to the new APIs and ensures a smoother phaseout process.

Future Plans

Chrome’s timeline indicates a significant shift in Q1 2025, with the start of the third-party cookie phaseout for all users. This gradual approach, in consultation with the CMA, aims to address any remaining competition concerns and ensure a fair transition for all stakeholders.
