German startup JAR is developing hack-proof hardware to replace passwords

JAR is a coin-sized device that can hold all your log-in credentials. All you need to do is plug it into the 3.5mm input of your smartphone, tablet or laptop, and you’ll be able to securely access your online accounts.

Developers of the JAR think their system is impossible to break in a lifetime. Their estimates say a hacker needs six quadrillion years to hack an account secured by JAR.

One the sides of the device are a fingerprint scanner and a small screen. Every time you want to access your account on a website, application, cloud storage or other services, you just plug it in and scan your finger.
