Google has added a two-factor authentication option to Google Apps, to provide additional protection against phishing and malware attacks, as the one-time codes are valid for a limited period, said Eran Feigenbaum, director of security for Google Apps.
Google will send out authentication codes by SMS (Short Message Service) or voice message. The SMS service will be free and available in 19 countries including Australia, Denmark, France, Germany, the Netherlands, Sweden, the U.K. and the U.S.
The authentication codes can also be generated locally using a smartphone app called Google Authenticator, available as a free download from the Android, BlackBerry or iPhone app stores. Apple has already approved the Google app for the iPhone and all three apps are now available, Feigenbaum said. More Info on Google Enterprise Blog
