2-factor authentication is one of the best way to prevent hackers from getting in to your Android smartphone/tablet or on your Gmail account. Two-factor authentication helps you to protect yourself from hackers and unauthorized access. According to WikiPedia, “Google was one of the first Internet companies to introduce two-step verification process.”
When you enable two-factor authentication either on Google account or on Facebook, you will receive an SMS code on your mobile phone as your second step of verification. If you want to prevent hackers from hacking your personal accounts i.e., Gmail, Yahoo, Facebook, then you must enable two-factor authentication on your accounts because the hackers will not be able to verify the second step unless they have the SMS verification code.
