CHIPS is a Privacy
Sandbox proposal that introduces a mechanism to opt-in to having third-party
cookies partitioned by top-level site using a new cookie attribute,
Partitioned.
The experiment started in Chrome 100 on March 29, 2022 and was scheduled to run
until June 14, 2022.
To give developers more time to test the feature and gather more feedback, an
extension to the experiment will run through Chrome 104 until the release of Chrome 105, on August 30, 2022.
Starting in version 103, Chrome will include an alternative CHIPS origin trial design for HTTP
cookies, which should enable an opt-in mechanism that will make deployment
easier for large organizations.
In the new design, sending Accept-CH: Sec-CH-Partitioned-Cookies header will
no longer be required to enroll in the origin trial. Sites will only need to
send the Origin-Trial header with their CHIPS origin trial token when they are sending
responses that include the Set-Cookie header with the Partitioned
attribute.
To enroll in the origin trial and start experimenting, head over to
CHIPS origin trial instructions.
