Block Third-Party Cookies in Google Chrome
Source-checked About 10 minutes
Answer
Open Chrome Settings > Privacy and security > Third-party cookies and choose Block third-party cookies. Add a narrow exception only if a trusted site breaks.
Know what this control covers
Blocking third-party cookies limits cookies created by sites other than the one in the address bar. It does not stop every form of tracking, remove existing first-party data, block ads, or replace the privacy and consent settings of websites you use.
Open Chrome's cookie settings
On a computer, open Chrome > More > Settings > Privacy and security > Third-party cookies. On a managed browser, a building or policy icon can indicate that the organization controls the setting.
Block third-party cookies
Choose Block third-party cookies. Review related-site and other options shown on the same page instead of assuming every embedded sign-in or payment flow will continue to work unchanged.
Test important websites
Reload the sites you rely on for sign-in, payments, document embeds, or media. If one trusted service breaks, note the domain and exact feature before weakening the global setting.
Create the narrowest exception
Under Sites allowed to use third-party cookies, add only the trusted site that needs access, or use Chrome's temporary address-bar control. Avoid broad wildcard exceptions unless every subdomain is necessary.
Remove old exceptions and data separately
Periodically review the exception list and remove sites no longer needed. Deleting cookies is a separate action that can sign you out and remove saved site preferences, so select a specific site's data when broad deletion is unnecessary.

If it does not work
- If a page still tracks or personalizes content, review Chrome's Ad privacy settings and the website's own account and consent controls; third-party-cookie blocking alone is not a guarantee of anonymity. If a managed policy prevents changes, contact the administrator rather than launching Chrome with unsupported flags.
