TechCrunch: Google is rolling out a new two-factor authentication feature that makes it harder for criminals to phish, hack or otherwise access user accounts. Google Apps users have had access to the service since September, but soon it will be available to everyone who wants to use it.
In order to use the two-factor authentication, users will need an Android, iPhone or BlackBerry smartphone and an app called Google Authenticator. The app sends a temporary passcode to users' phones. They must then enter the passcode, along with their usual password and user id, in order to access Google services like Gmail.
