Your Pinterest account is about to be safer than ever. EyeLock, a company known for making iris scanners for security checkpoints at banks, recently introduced an at-home device called Myris ($280). It stores your passwords locally, instead of in the vulnerable cloud, and encrypts them. The only way to access them is by scanning your eyeball.

Setup is simple: Plug the palm-size Myris into your computer's USB port and look into the camera. Once it has identified and logged some 240 unique points in your iris, you can create a username and add your passwords. After that you never have to type a password again. Just sign in with your eye when you turn on your computer and all of your passwords are automatically input, except for time-sensitive passwords for things like banking sites, for which you'll need a rescan to access. When Myris runs smoothly, you wait about ten seconds and see a brief flash of light. But when the device acts up, which in our tests was a little less than half the time, expect a few retries—and to see spots for a minute or so after.

It's impressive, and it's allegedly unhackable. While fingerprints offer about twenty points of difference, the human iris has twelve times that. Not even identical twins have the same iris texture. The only downside, other than those pesky (but temporary!) blind spots, is that in order for Myris to work, you need to have it with you. So if you have your laptop but forgot your fancy new scanner, or if you're checking your email from your phone, you'll still have to type in your password. Which will be even harder to come up with after months of not having to remember it. (Hint: It's your dog's birthday.)
