Google’s Chrome browser has a syncing feature similar to Firefox to sync your saved passwords and other browser data/settings with other computers and devices. By default, however, Chrome only encrypts your saved passwords when syncing your browsing data across the Internet to your other computers and devices. Because the only password needed to sync new computers and devices is your Google password, should someone else know your Google password or your account gets hacked, they can sync with your browser data and gain access to your all of you saved passwords, which is potentially very dangerous.

There is are two additional safety measures you can take to make syncing more secure. You can choose to encrypt all synced data and you can also create your own encryption passphrase for synced data. When you create your own passphrase, it will be used to encrypt and decrypt your synced browsing data instead of your Google account password. Thus when you setup a new computer or device to sync with your browsing data, you must login to your Google account and then also enter your sync passphrase.

To change your syncing settings for Chrome, click the Wrench icon > Settings > Advanced sync settings and you’ll see a pop-up window where you can make these changes.

An alternative is to not use Chrome to store your login passwords for websites and instead install and use a separate password management application such as LastPass. That way, your passwords will not be stored with your synced browser information at all.
