FAQs
What is happening to third-party cookies in Chrome?
Chrome is proposing a new experience for user choice with third-party cookies. To preserve critical user experiences, you need to prepare your site for users who choose to browse without third-party cookies.
What were the third-party cookie deprecation trials?
Chrome's third-party cookie deprecation trials were a mechanism for sites or services experiencing breakage to request additional time to migrate away from third-party cookie dependencies.
Successful deprecation trial applicants were granted a grace period, providing continued access to third-party cookies while trial tokens were being deployed. These trials are no longer offered, but origins that were approved for a trial will continue to have access to the grace period.
To apply for grace period access, if you were not a deprecation trial participant, you must report features that will be broken by third-party cookie changes at goo.gle/report-3pc-broken.

Why can't I access the deprecation trial ticket link shown for my grace period?
Deprecation Trial ticket access is intentionally restricted to the Google Account that applied for the trial.
Contact the applicant within your organization in order to view the ticket.
What is the grace period?
When a breakage report is filed at goo.gle/report-3pc-broken and verified for a site, Chrome initiates a grace period that provides continued access to third-party cookies for a limited time.
This dashboard displays any grace period that affects a domain which is same-site to the queried URL.

What is the opt-out mechanism?
The opt-out mechanism allows sites to offboard from the grace period in a self-service fashion.
If an opt-out configuration file is fetched, this dashboard displays its status and the active value.
Why hasn't my opt-out value been picked up?
If the entry for your grace period says "fetched: false", double check that the opt-out configuration file is accessible at the provided directory.
If the entry for your grace period says "valid: false", you can validate your file against the schema on the validation page.
If the file is fetched and valid but the value is outdated, allow one business day after modification for the dashboard to pick up the new value.
What is the freshness of this dashboard?
The "last published" timestamp for each entry displays the last time the data was synced and published.
Grace periods and opt-out values will take effect on the client within 24 hours of this timestamp.
