Would you trust your heart more with your passwords than your brain?
I've never trusted multi-factor authentication because when you really need help logging in, you've probably forgotten your password, lost your wallet and your phone. What we need is a secure way to log in that doesn't rely on our brain to remember simplistic passwords.
The Nymi bracelet, from Bionym, can securely manage your passwords, and even make payments, because it relies on your electrocardiogram, a measure not of your heart rate but of the electrical activity generated by your heart. Once the clasp is broken, or the Nymi is removed from your body, it becomes obsolete.
