Block third-party cookies in Chrome on a computer

Reduce cross-site cookie tracking. Keep normal sign-in cookies, then check that your usual sites still work.

4 steps

  1. Open Chrome settings

    Do this
    Click the three-dot menu at the top right, then Settings.
    You should see
    A Settings tab opens with a list on the left.
    Undo or troubleshoot
    Close the tab; nothing has changed yet.
  2. Go to Privacy and security

    Do this
    Choose Privacy and security, then Third-party cookies.
    You should see
    You see options for how third-party cookies are handled.
    Undo or troubleshoot
    If you cannot find it, use the search box at the top of Settings and type "cookies". If your device is managed by work or school, some settings may be locked; ask your administrator instead of trying to override them.
  3. Block third-party cookies

    Do this
    Select Block third-party cookies.
    You should see
    The option is selected. Your existing sign-ins remain.
    Undo or troubleshoot
    Select your previous option to return to how it was.
  4. Test the sites you rely on

    Do this
    Open one site you sign in to, play a short video, and go to a shop's checkout page without paying. Reload each once.
    You should see
    Sign-in, playback and the checkout page work as before.
    Undo or troubleshoot
    If one site breaks, undo only the last change you made, or add an exception for that one site. Do not switch off all protection, and do not clear all cookies by default — that signs you out everywhere. In Chrome you can allow cookies for one site from the same Third-party cookies page under sites allowed to use third-party cookies.
