Google Introduces Two-Factor Authentication Option

Users can now generate a second, one-time password for Gmail and other accounts using a mobile phone

In an effort to help users increase the security of Gmail and other accounts, Google today introduced an option to add a second factor of authentication.
As we announced to our Google Apps customers a few months ago, weve developed an advanced opt-in security feature called 2-step verification that makes your Google Account significantly more secure by helping to verify that youre the real owner of your account, Google says. Now its time to offer the same advanced protection to all of our users.
Two-step verification requires two independent factors for authentication: a password, plus a mobile phone-generated code the user only uses once.
It might take up to 15 minutes to enroll in the two-factor program, Google says. Once you enable two-step verification, youll see an extra page that prompts you for a code when you sign in to your account, the company says. After entering your password, Google will call you with the code, send you an SMS message, or give you the choice to generate the code for yourself using a mobile application on your Android, BlackBerry or iPhone device.
By logging on with a one-time code as well as a password, well have a pretty good idea that the person signing in is actually you, Google says.
With the two-factor program, a user will need both the users password and the users phone, Google observes. A hacker would need access to both of these factors to gain access to your account, the company says.
Users can choose a Remember verification for this computer for 30 days option, which means they wont need to re-enter a code for another 30 days.
