Google announced today that it is adding two-factor verification for Google Applications. This will allow users to set up a one-time code delivered to a mobile phone, in addition to a regular password. Currently this option is only available for paid Google apps, although it will be available to all users in the coming months. If an administrator of a paid Google Apps account enables two-factor verification, then all users will be required to submit their mobile phone number. Google Apps operate by using cloud computing. In March 2009, EPIC filed a complaint with the Federal Trade Commission over Google's lack of adequate safeguards for its Cloud Computing Services. For more information, see EPIC: Cloud Computing.
