Chrome's third-party cookie deprecation trials: grace period extended
To ensure sites have enough time to migrate away from third-party cookie
dependencies, Chrome has provided first-party and
third-party deprecation trials to temporarily re-enable
cookies.
To minimize user friction while sites apply for and deploy tokens for the
deprecation trials, Chrome implemented a grace period to temporarily re-enable
third-party cookies for sites with reported user-facing
breakage. During the grace period, origins
registered for a deprecation trial can access third-party cookies in Chrome even
if they have not yet deployed trial tokens. The grace period was due to end on
April 1; however, Chrome has received feedback that sites and services need
additional time to implement their deprecation trial tokens.
The grace period will continue until June 30, 2024 for sites and services
needing additional time to deploy their deprecation trial tokens. This
extension applies to both the first-party and
third-party deprecation trials, covering first-party
(top-level site) and third-party (service provider) use cases.
We encourage sites and services to implement deprecation trial tokens as
quickly as possible to allow for more fine-tuned testing of third-party cookie
deprecation readiness. The grace period and deprecation trials are available for
sites and services that meet the
eligibility criteria.
Participating origins must deploy deprecation trial tokens before the extended
grace period expires to preserve access to third-party cookies.
