11. Check ALL of your Facebook settings once per month, and make sure they stay the same. Really important on mobile apps. I find if I delete the app and then reinstall it, all my settings go back to default. Understand each setting.

12. Turn on all security features like two-factor authentication. People who do that generally don’t get hacked. Don’t care? You will when you get hacked. Do the same for your email and other social services too.
