Google has announced today that soon every Gmail user will be able to protect their Gmail account from hacking by using 2 step verification processes.
We have seen many people lost their Gmail account and thus personal & sensitive information when someone guesses their password. To stop such incident Gmail user will soon be able to use this features.
It includes your password and a mobile generated code. Even if hacker got your password, he will have to enter the secret code to gain access to your Gmail account. This is really a good initiative from Google as maximum people use Gmail.

Why you should use 2-step verification
2-step verification adds an extra layer of security to your Google Account by requiring you to have access to your phone – as well as your username and password – when you sign in. This means that if someone steals or guesses your password, the potential hijacker still can’t sign in to your account because they don’t have your phone.
How you sign in with 2-step verification
- When you want to access Google products from your browser, go to that product and enter your username and password.

- You’ll next be prompted to enter your verification code, which you’ll get from your phone. You’ll only have to do this once every 30 days if you so choose.

- Soon after you turn on 2-step verification, non-browser applications and devices that use your Google Account (such as Gmail on your phone or Outlook), will stop working. You’ll then have to sign in using your username and a special password you generate for this application. (Don’t worry, you’ll only have to do this once for each device or application.)
