Chrome Sync Is Paused Every Time You Restart? Fix It

If Chrome sync is paused every time you restart the browser, the problem is almost never sync itself. Chrome is throwing away your Google sign-in cookie when you close the last window.

Change one setting, under Privacy and security > Site settings > Additional content settings > On-device site data, to Allow sites to save data on your device.

Who this applies to

Browser: Google Chrome on Windows, Mac, Linux, and ChromeOS. Not version-specific.
Account: A personal or work Google Account with sync turned on in Chrome.
Symptom: A Sync is paused or Verify it’s you message in the top right, over and over, even though you keep signing in.

Why Chrome keeps pausing sync

There are three common causes, and they look different from each other. Find the one that matches what you see, then jump to that fix.

It happens on every single restart. Close Chrome, open it, and the message is back. This is a site data setting. Chrome is deleting your Google cookies on exit, so the next launch has nothing left to prove you are signed in.
It happens right after you sign out of Gmail, YouTube, or another Google site. This one is on purpose. Google’s own help pages say that signing out of a Google service pauses Chrome sync and asks you to verify it’s you.
It happens at random, and the site data setting is already correct. Something outside Chrome is wiping your cookies. That is usually a cleaner, a privacy tool, an antivirus product, or an extension.

Fix 1: stop Chrome from deleting site data on exit

This is the fix for the every-restart case, and it is the one almost everybody misses. The control has nothing to do with the sync section of Settings. It lives four levels deep in the privacy settings, and it does not even appear in the main Site settings list until you expand a section.

Open Chrome and select More (the three dots in the top right), then Settings.
Select Privacy and security in the left sidebar.
Select Site settings. Be careful here. Third-party cookies sits two rows above it on the same page, and that is the row most people click by mistake. It is not the one you want.
Scroll down and select Additional content settings to expand it.
Select On-device site data.
Choose Allow sites to save data on your device.

The other two options on that screen are what break sync:

Delete data sites have saved to your device when you close all windows. This is the usual culprit. It does exactly what it says, and your Chrome sign-in is stored as site data.
Don’t allow sites to save data on your device. Google marks this one as not recommended. Sync will not survive it.

One thing to know before you test it. The change only protects cookies written from that point forward. It does not bring back the one that was already deleted. So sign in once more, then quit Chrome completely and reopen it. That second launch is the real test, not the moment you flip the setting.

If you want to keep deleting site data

Some people wipe site data on close on purpose. Chrome lets one site override your default, so you can keep the strict setting everywhere else.

Go to accounts.google.com and sign in.
Select View site information, the icon to the left of the web address.
Select Site settings.
Find the on-device site data control for that site and set it to allow.

Your default still applies everywhere else, so the rest of the web is still cleared when you close Chrome.

Fix 2: resume sync after signing out of a Google site

If the message showed up right after you signed out of Gmail or another Google service, nothing is broken. Chrome paused sync on purpose and is waiting for you.

Select Verify it’s you in the top right of Chrome.
Select Sign in again.
Sign in to your Google Account.

If you would rather this stopped happening, stay signed in to your Google Account in the browser instead of signing out of individual Google sites.

Fix 3: find what else is clearing your cookies

If the site data setting was already correct, something else on the machine is deleting cookies behind Chrome’s back. Google’s account help says this directly: some antivirus and related software delete your cookies.

Work through these in order, restarting Chrome after each one.

Go to Extensions and turn every extension off. Restart Chrome, sign in, then quit and reopen. If sync holds, an extension was the cause.
Turn your extensions back on one at a time, restarting after each, until the message returns. Start with anything that mentions privacy, cookies, cleaning, or auto-delete, because those are the usual culprits.
Open any PC cleaning or tune-up tool you have installed and look for a browser cleaning schedule. Turn off the part that clears cookies.

The next step involves your security software. Change one setting only, put it back if it does not help, and never turn protection off entirely just to test this.

In your antivirus or privacy suite, look for a browser privacy, tracker cleaning, or cookie cleaning feature, and turn off automatic cookie deletion.

What does not fix this

These are the things people try first, and they are the reason this problem drags on for weeks.

Signing in again. It works, briefly. Sync resumes and looks healthy. Then you close Chrome, the cookie is deleted again, and you are back where you started. Signing in is not a fix, it is the symptom repeating.
Turning sync off and back on. The sync switch is not what is broken. Your settings, bookmarks, and passwords were never the problem, so resetting them changes nothing.
Clearing your cache and cookies. This is the standard advice for almost every browser problem, and here it makes things worse. Google warns that deleting cookies signs you out of sites that remember you. You are performing the failure by hand.
Reinstalling Chrome or deleting the profile folder. On Google’s own support forum, someone reported resetting settings, uninstalling and reinstalling Chrome, and deleting the whole user data folder. The message came back. A reinstall lands on whatever default that machine has, and a synced profile brings your preferences back with it.
Changing the third-party cookie setting. Wrong screen. It sits close to the right one in Privacy and security, which is why so many people end up there, but it governs cookies set by other sites inside a page. Your Chrome sign-in is not a third-party cookie.

Frequently asked questions

Why does Chrome say sync is paused when sync is still turned on?

Paused and off are two different states. Sync stays turned on, with all your choices intact, but Chrome has lost the proof that you are signed in to your Google Account, so it stops sending data until you confirm who you are. That is why the sync toggle looks perfectly fine while the warning sits there.

I already allow sites to save data on my device, so why is sync still pausing?

Then the setting is not your cause. Something outside Chrome is deleting cookies: a cleaning tool, an antivirus product, or an extension. Turn all your extensions off, restart, and see whether the message stops. Fix 3 walks through the rest.

Will I lose my bookmarks and passwords while sync is paused?

No. What is already on the device stays there. New changes just stop travelling to your other computers and phones, so your devices drift apart until you sign in again.

Is it safe to let sites save data on my device?

It is Chrome’s normal behaviour and the option Google recommends. Sites use it to keep you signed in and to remember things like a shopping cart. If you want tighter privacy, keep the stricter default and add the per-site exception for your Google sign-in instead.

In short

A paused sync message that returns on every restart is a site data problem wearing a sync costume. Set On-device site data to allow, sign in once more, then quit and reopen Chrome to confirm it held. If it returns, the cause is outside Chrome, and the extension and antivirus checks are where to look.
