Google's latest introduction in to personal security, password management offers even more secure way than the usual two-step smartphone method. A USB also doesn't require batteries or a mobile connection, so it can work anytime anywhere. Think about if your phone is dead and your notebook is on it's last breath of battery life and you need to login to Google to send that email with proposal that you spent last few hours preparing. The Security Key uses the open Universal 2nd Factor (U2F) protocol from the FIDO (Fast IDentity Online) Alliance, and it will be compatible with any site that follows the suit
Even with the level of security it offers, the USB based Security Key only works if the website is verified to be legitimately coming from Google. This will block out phishing attempts and fake sites that would attempt to make you send the credentials to them.
Google's Security Key implementation only works, at the moment, with Google Accounts and on the Chrome browser, specifically version 38 and later only. But I am sure the space will widen.
