To enable third-party cookies in Chrome, open Settings > Privacy and security > Third-party cookies and select Allow third-party cookies, or use the per-site exception list to grant access to specific domains only.
A site that refuses to load, keeps kicking you out, or shows a garbled login screen often points to one thing: Chrome has third-party cookies turned off. The browser’s default move is to block them, which breaks features like embedded videos, payment widgets, and cross-site sign-ins. The fix is two settings deep and takes about ten seconds.
Where the Third-Party Cookie Setting Lives in Chrome
Chrome groups all cookie controls under one privacy section. On a computer, the path is the same across Windows, Mac, and Linux.
Open Chrome and click the More icon — three vertical dots in the top-right corner. Select Settings, then Privacy and security from the left panel. Click Third-party cookies. You will see three options: Allow third-party cookies, Block third-party cookies (the default), and Block third-party cookies in Incognito.
Choosing Allow third-party cookies flips the global switch on. Any site that relies on cross-domain cookies will start working immediately in new tabs.
The Per-Site Exception List: Grant Cookies to One Domain Only
Blocking third-party cookies globally is safer for privacy, and most sites work fine under that setting. If only one site is broken, add it to the allowed list instead of turning cookies on for everything.
In the same Third-party cookies section, scroll to Sites allowed to use third-party cookies and click Add. Enter the site’s domain — for example, example.com — and click Add. Google supports prefixing the domain with [*.] to match all subdomains. You can also enter an IP address or a web address without the http:// part.
The site now appears on the allowed list, and its third-party cookies will be accepted even when the global block is active.
Using the Page-Specific Cookie Prompt
Chrome sometimes shows a small cookie icon in the address bar when a site requests third-party cookies. Click the icon to see a panel that says Third-party cookies blocked. Flip the toggle to Third-party cookies to allow them just for that tab. Turning it back off blocks them again for the same site. This per-prompt method is the fastest option when you are already on the page that needs cookies to load properly.
| Method | Scope | Best For |
|---|---|---|
| Global allow in Settings | All sites | Fixing multiple broken sites at once |
| Per-site exception | One domain | Keeping the global block on while unblocking a single site |
| Address-bar cookie prompt | Current page only | A quick temporary fix without changing Settings |
| Incognito-only allow | Private browsing | Testing sites without affecting your regular Chrome profile |
What to Do When Enabling Third-Party Cookies Still Doesn’t Work
Sometimes the cookie setting is correct but something else is interfering. Try these fixes in order before digging deeper.
Close and reopen Chrome completely. A fresh browser window sometimes picks up the setting change that a long-running session missed. Next, clear your cache and cookies via Settings > Privacy and security > Clear browsing data — check the boxes for Cached images and files and Cookies and other site data, then click Clear data. If the site still fails, test the same page in an Incognito window. Incognito starts with no extensions or stored data, which isolates the problem to a cookie setting or a browser extension conflict.
Google also notes that browser-level privacy settings or third-party extensions can override cookie controls. If the site works in Incognito, the culprit is probably an extension. Disable extensions one by one under More > Extensions > Manage extensions until the site loads correctly.
| Problem | Likely Fix |
|---|---|
| Site loads but sign-in fails | Check per-site exception list — the domain may be blocked globally |
| Global setting keeps reverting | Turn off browser-level privacy tools or security software that manages cookies |
| Works in Incognito but not normal mode | An extension is interfering — test by disabling extensions |
| No cookie icons or prompts appear | Chrome may need an update; check About Google Chrome |
How to Enable Third-Party Cookies on Chrome for iPhone and iPad
Chrome on iOS uses the system-level WebKit engine, so the cookie control lives outside the Chrome app itself. Open your iPhone or iPad Settings, scroll down to Chrome, and tap it. On the Chrome settings page, toggle Allow Cross-Website Tracking on. That enables third-party cookies and cross-site tracking across all sites Chrome loads. This setting is separate from Safari’s privacy controls, so changing it in Chrome does not affect Safari, and vice versa.
