Google launched an advanced security feature called two-step verification system earlier in the year for Gmail and Google Apps (last year) that makes your Google Account significantly more secure by providing an additional layer of security.
The two-step verification process relies on something you know (your password) and something you have (your mobile phone).
This two-way verification is not new. Quite a few banks have been using this system for quite a while, allowing users to access their website using a unique passcode generated by a security token given by the bank and the password.
Last month, Google released an iPhone app called Google Authenticator for the two-step verification for the iPhone. Google Authenticator app basically turns your iPhone into a security token and generates a unique passcode for the two-step verification.
You can checkout how the two-step verification system works in the demo video:
You may also go through the the details about the two-step verification system on this webpage on Google’s website before setting it up.
It is highly recommended that you enable the two-step verification if you have a Google Account. The entire setup process does not take more than 5 to 10 minutes. And if you do then Google Authenticator is a must-have app and you can download it from the App Store for free using this iTunes link. You can also use the app on your iPad or iPod touch.
Please stay safe and pass this around to your family and friends who have a Google Account as well.
