How to Setup Gmail 2-Step Verification With Android

Ever wonder how terrible if your Gmail got hacked by someone and stole all your work data, bank account, and other important data? That must be a nightmare and nobody  ever wants it to happen. Gmail currently has an advanced  sign-in method that enable you to pass two steps of verification whenever you want to login to your Google account.

This  2-steps verification requires two independent factors for authentification. This is much like you might see on your e-banking transaction, your website password and a key obtained from your phone or a dedicated key generator device. Once this 2-steps verification enabled on your account, you will see an extra page prompting for a code after you signing in with username and password. You can use your Android, Iphone or Blackberry as the code generator device or  use SMS to send the code to your phone.
