If a company wanted to add the security they can choose to from the Google administrator console. The next time a user logged into Google apps they would choose some security questions and the software would be downloaded on to their computer. The user would continue to use a user name and password for access but the software on the computer would provide another layer of authentication, Alexander says. If a user logs in from a computer that doesn’t have the software, he will have to answer some security questions to gain access to the services.

Companies that decide to use the service are charged $1 per user per month, Alexander says. “It’s getting more important that companies have security and the authentication services that are better than user name and password,” she says. “This makes it easier to get strong authentication without the headaches of installing servers.”
