On its official blog, Google notes that Google Apps Premier, Education and Government Edition administrators can implement a new sign-in process that requires users to use a combination of a password and a one-time verification code delivered through users' mobile phones.
This is how it works: When Google Apps users sign-in from a certain location, they have to enter in not only their user password, but also a code that is generated either by an SMS message, a voice call or from an app installed on their mobile phone.
According to Google, the feature will be added to Google Apps Standard Edition as well as individual Google users in the coming months.
The company also mentioned its plans to launch mobile editing in Google Docs for Android and the iPad "soon," and that 3 million businesses (and 30 million users within those businesses) are now using its messaging and collaboration tools.
