If your copy of Google Chrome hasn’t been updated in the last four years, your bookmarks, extensions, and browsing data could soon stop syncing across devices. Google announced this week that Chrome Sync, the feature that seamlessly links your browser activity to your Google Account, will no longer work on versions of Chrome older than four years starting in early 2025.

The cutoff: why four years?

Google hasn’t specified an exact version number for the cutoff, but the message is clear: if your browser hasn’t seen an update since 2021 or earlier, it’s time to upgrade. Users clinging to outdated versions will encounter one of two warnings: “Update Chrome to start sync” or “Update Chrome to keep using the Chrome data in your Google Account.”

This move isn’t entirely unexpected. Google has long prioritized security and performance improvements in Chrome, which sees updates every few weeks. Older versions lack critical security patches, making them vulnerable to exploits. By sunsetting Sync for these browsers, Google aims to nudge users toward safer, more modern software.

What’s at risk?

Chrome Sync allows users to access:

• Bookmarks
• Extensions and themes
• Browsing history
• Open tabs
• Passwords (though these now sync automatically)

Notably, Google has already decoupled some features from Sync. Since 2023, passwords, addresses, and payment details automatically sync when you sign into Chrome, even if Sync is turned off. However, bookmarks, extensions, and history still require Sync to be manually enabled.

Why this matters

While four years may seem like a generous grace period, outdated browsers pose significant risks. According to a 2023 report by Cybersecurity Ventures, 60% of data breaches involve unpatched vulnerabilities. Older Chrome versions lack protections against modern phishing schemes, malware, and zero-day exploits.

How to stay protected

• Check your Chrome version: Go to Settings > About Chrome. If it’s been a while, let the browser update.
• Enable auto-updates: Chrome typically updates automatically, but ensure your system isn’t blocking them.
• Export data as a backup: Use Chrome’s Bookmark Manager or third-party tools to save critical data locally.

The bigger picture: Google’s shift toward frictionless syncing

Google has been quietly reducing reliance on Chrome Sync for years. Features like password autofill and cross-device tab sharing now work without requiring Sync to be enabled. This shift aligns with industry trends toward seamless, account-based integrations—think Apple’s iCloud Keychain or Microsoft Edge’s built-in sync.

Yet, the move also underscores Google’s emphasis on privacy and security. Older browsers lack protections like Enhanced Safe Browsing, which blocks malicious sites in real-time. By deprecating Sync for outdated versions, Google effectively draws a line in the sand: update or lose functionality.

What’s next?

The change will roll out in early 2025, giving users and organizations time to adapt. While Chrome’s update process is largely hands-off, those who’ve disabled updates (common in enterprise environments) will need to act.

For most, though, the fix is simple: keep Chrome updated.
