There are application downloads and passwords set in my boyfriend’s Chrome Sync. He says that he did not do any of it….. how can that be possible?
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.
