Protect your synced data

When you sign in to Chrome and enable sync, Chrome keeps your information secure by using your Google Account credentials to encrypt your synced passwords. Alternatively, you can choose to encrypt all of your synced data with a sync passphrase. This sync passphrase is stored on your computer and isn't sent to Google.

Adjust encryption settings

Windows, Mac, and Linux instructions

  1. Click the Chrome menu Chrome menu on the browser toolbar.

When you’ll need your encryption passphrase

If you decide to pick your own passphrase, you’ll need to provide it every time you sign in to Chrome on a new computer. If you change your encryption options on one computer, be sure to make the same change on any other computers to continue syncing. Note: Once you encrypt all your synced data with your own passphrase, it's not possible to go back to only encrypting passwords without resetting sync.

Forgot your encryption passphrase?

If you forget your passphrase, you’ll need to reset sync via the Google Dashboard. This will delete all synced data from Google’s servers and disconnect all synced computers and devices, but not the data that’s on your computers or devices. So your current preferences, bookmarks, and passwords will remain available in the browser. You can then re-enable sync with a new passphrase.
