6 Things That Could Replace Your Password

Biometrics are unique biological traits like facial features, fingerprints, and heart pulsations that help identify you as you. The Nymi from Bionym is a bracelet that taps into your heart’s rhythm to unlock compatible devices and operate smart environments (lighting, entertainment systems, kitchen settings, etc.). Also, you can also use it to pay for a double shot espresso.

But the Nymi has its problems. For one, it looks similar to a — *shudder* — Livestrong bracelet. Second, it’s still crackable. And a hacker with your heartbeat is exponentially worse for you than a hacker with your password.
