6 Things That Could Replace Your Password

1. YOUR HEARTBEAT
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.
