It just got a little easier to log into Gmail. Today, Google launched support for Security Key, an open standard that lets you log in to an account with a physical device, usually in the form of a USB. The device takes the place of the six-digit confirmation codes currently used by Google’s two-factor authentication. Instead of typing in the code, you’ll simply insert your USB key before logging in. A password is still required, so a thief wouldn’t be able to log into your account just by stealing your security key. On the other hand, if your account password ended up leaking onto the web, it would be useless without the corresponding security key.
