What data synchronizes reset the phone with an old Google account?

Sold in the summer last phone, before it dropped through the settings to the factory condition. Last month looked at the "recently used" device, my old device synced many minutes ago. Changed the password, is a two-step authorization. Then again, almost every day, the phone is synchronized with your account. Close access is impossible.
How is this possible? What he synchronizes?
