Google Rolls Out Two-Factor Authentication For Everyone. You Should Use It.



Given how much data we’re trusting to online sites these days — email, search history, even voice calls — the repercussions to having our account passwords phished, hacked, or guessed are worse than ever. Unfortunately as far as consumers are concerned, account security has been stagnant for years: nearly every service requires a username and password, and that’s it. Cue the scary music and a Dateline special on having your identity stolen.


The feature is called two-factor authentication, and it’s been available to Google Apps customers since September. Now it’s rolling out to everyone. It’s a bit confusing and the set-up process will probably intimidate a lot of people, but it’s well worth looking into if you value your account data. You can activate it by hitting the ‘two-step verification’ link on this page. So what exactly does it do?

In short, it makes it so that when you go to login to your Google account, you need to enter both your existing password and a special new second passcode — one that you don’t have to write down or memorize because it’s always changing, so it’s nearly impossible to phish. You generate this second password by firing up a new mobile app available for Android, iPhone, and BlackBerry called ‘Google Authenticator’, or by having Google call or send you a text message to a phone number you entered when you set up the feature. That password will expire in just a few minutes though, so be quick (and yes, you will feel like a secret agent the first few times you use it).
