Google announced today that they now support 2-factor authentication, or what they're calling 2-step verification. This combines your normal username and password that you use to login with a 2nd piece of information to authenticate yourself when logging in to your account. This 2nd piece of information comes in the form of a series of numbers that Google provides to you via text message, phone or a brand-new app called the Google Authenticator each time you want to login to Gmail. This numerical code changes every time you login, so even if your password is compromised, a hacker can't access your account unless they also have your phone. Given how much information we exchange via email these days, and how Google encourages everyone to save all of their email in Gmail, it's important to keep your Google account secure, so I recommend enabling this feature today.
