Frequent logout of Chrome is usually caused by synchronization issues, cookie settings, extensions, or browser versions that are too old. 1. Synchronization problems or user profile corruption may cause Chrome to fail to synchronize data normally. Solutions include checking the synchronization status, turning off and restarting synchronization, or deleting and re-adding user profile. 2. If the cookie settings are too strict or automatically clearing cookies will interrupt the login status. The option "Clear Cookies when closing the window" should be turned off. 3. Some extensions (such as ad blocking tools) may interfere with login, and you can pass traceless mode testing and disable extension troubleshooting one by one. 4. Using an outdated Chrome version may also cause this problem and need to be updated to the latest version to fix the vulnerability.

Chrome keeps signing you out because of a few common reasons—none of which are necessary your fault. It usually comes down to how Chrome manages your profile, sync data, cookies, or extensions. Here's what might be going on.

Sync issues or profile glitches

One of the most common causes is a problem with Chrome's sync system or your user profile. If Chrome can't properly sync your data with your Google account, it may log you out as a fallback.

• Sometimes, switching between accounts or syncing large amounts of data can cause instability.
• Corrupted profile files stored locally can also lead to unexpected sign-outs.

What to do:

• Go to Settings > You and Google > Sync and make sure sync is turned on and working properly.
• Try turning sync off and then back on again.
• If that doesn't help, go to Settings > Profile > Manage profiles , and try removing and re-adding your profile.

Cookie settings or clearing browser data

If your cookie settings are too strict or you've set Chrome to automatically clear cookies when you close the browser, this can kick you out of accounts—including your main Google account in Chrome.

• Automatic cookie clearing happens under Settings > Privacy and security > Cookies and other site data .
• Some people enable this for privacy but don't realize it affects login persistence.

To check:

• Make sure “Clear cookies and site data when you close all windows” is off , unless you're OK with being logged out regularly.
• Also, avoid manually clearing cookies too often if you want to stay signed in.

Extensions or third-party software interfering

Some extensions—especially ad blockers, privacy tools, or script blockers—can interfere with how Chrome maintains login sessions.

• This is more common than you'd think. Tools like uBlock Origin, Ghostery, or even antivirus browser plugins can mess with cookies or scripts that keep you logged in.
• In some cases, malware or poorly coded extensions can also be the culprit.

Try this:

• Open Chrome in Incognito mode (which disables most extensions) and see if you still get logged out.
• If not, one of your extensions is likely the issue.
• Disable them one by one to find the troublemaker.

Outdated Chrome version or bugs

Using an outdated version of Chrome can lead to unexpected behavior, including getting signed out.

• Chrome updates frequently fix bugs related to sign-in and sync.
• If you haven't updated in a while, that could be why things aren't working smoothly.

Fix:

• Go to Settings > About Google Chrome to check for updates.
• Let it update and restart the browser.

It's usually not just one thing causing the problem—it's a mix of settings or background processes not working together right. Start with the easiest fixes first: check your sync status, review cookie settings, and test without extensions. Once you rule those out, move on to updating or resetting your profile.

Basically that's it.
