How to secure your Google, Gmail and android account
Google offers 2 step verification. This means that you need your password, user name and a verification code. They send the verification code to you every 30 days or you can download an app that will generate a new verification code.
Using 2-step verification is a really good safety measure. It means you can secure your email account and your mobile which is very important. If you use Google other products such as storing photos or documents online those will be more secure as well.
