The Titan Security Key is a two-factor authentication tool that Google employees use internally to eliminate phishing; the company has since made it available to the public. The key works like a car fob, unlocking devices at the press of a button. The $50 bundle includes USB and Bluetooth keys that can be set up in a minute.
