To facilitate testing, Chrome has restricted third-party cookies by default for 1% of users. Subject to addressing any remaining competition concerns of the UK's Competition and Markets Authority (CMA), Chrome will ramp up third-party cookie restrictions to 100% of users from Q3 2024.
During this testing period, it is important for sites and services to start preparing for third-party cookie restrictions, including moving to more private alternatives.
To help you prepare, this February we are hosting the 12th edition of Privacy Sandbox office hours, where we will provide some Privacy Sandbox tester updates and answer your questions with product and technical leads. This set of webinars will focus on the testing and preparing for the current 1% restriction of third-party cookies in Chrome along with use of Mode A and B available as part of Chrome-facilitated testing.
