If you use sensitive Google services (e.g. Gmail) and want to protect your account from potential hackers, click on the picture of your face (top right) and do "Account Settings". Then next to "Using 2-step verification" click Edit. Then there's a wizard which sends you something via SMS text, and calls you to confirm automatically too. Then you use your cellphone to confirm when you log in from a new computer. It's free, and totes awesome. Means people can't get ye stuff, even if they get your password.
