The system enables users to set up a method for obtaining a secret code that will be required, along with a password, to access a Gmail account. The new two-factor authentication system is a voluntary program right now, although it could become mandatory at some point in the future. Gmail, like virtually all other webmail services, has been a frequent target of attacks, both sophisticated and mundane, aimed at hijacking users' accounts. The most famous of these was an attack that was part of the Aurora operation against Google and others, part of which targeted the Gmail accounts of Chinese dissidents."
