Google’s 2-step verification technique goes beyond passwords, relying instead on mobile text messaging or mobile apps or even calling you directly at a phone. Google uses these communication options to deliver unique numbers independent of your browser or computer as an integral part of the Google Account log-in process.
Google will send you a number to be used in conjunction with your User ID and Password. This number is sent by text message, through use of an app, or by a phone call to you. This Unique Number constantly changes and separate log-ins even one-half hour apart would require different numbers for the final step in the login process.
Here’s one news account:
Note 2-step verification procedures have been available for the paid “Google Apps” users for 2 months.
In case you were unaware, there is a paid option for Google Apps (email account management, domain name and Web site hosting, etc.) with features different from Google’s free versions.
Here’s Google’s instructions and comment.
