Tamil Computing: Two Step Authentication from Gmail to prevent password hacks

Two-step verification

For the first time, we’re making it possible for organizations large and small to use this technology in just a few clicks for free. In the coming months, we’ll also be offering this same security to our hundreds of millions of individual Google users.

Two-step verification is easy to set up, manage and use. When enabled by an administrator, it requires two means of identification to sign in to a Google Apps account, something you know: a password, and something you have: a mobile phone. It doesn’t require any special tokens or devices. After entering your password, a verification code is sent to your mobile phone via SMS, voice calls, or generated on an application you can install on your Android, BlackBerry or iPhone device. This makes it much more likely that you’re the only one accessing your data: even if someone has stolen your password, they'll need more than that to access your account. You can also indicate when you're using a computer you trust and don't want to be asked for a verification code from that machine in the future.

Two-step verification is built on an open standard designed to allow integration with other vendors’ authentication technologies in the future. We are also open sourcing our mobile authentication app so that companies can customize it as they see fit.
