Hideez Key 2

Hideez Key is a single digital key for wireless authentication. In other words, this is a digital identity manager that allows you to do everything from store passwords to open doors to maintain a Bluetooth connection with your phone, laptop, or other device if it’s stolen. Branded as a “universal digital key designed to save time and give additional privacy and security to our digital lives,” the Hideez 2 comes with a hardware-encrypted password manager with second factor authentication, as well as RFID credential storage that lets you lock and unlock more than a thousand doors using this single wearable device. It also comes with a Bluetooth LE transceiver, which means you can unlock your mobile devices or laptops from a distance, and actually verifies your identity using your eye veins.

When the Hideez 2 becomes widely available this summer, it’ll come in four “easy-to-use form-factors — keychain fob, wristband, pendant or clip — each in a thin, water-resistant case” and set you back about $65. So if you need to keep your information secure, streamline your life, and otherwise become a denizen of the 21st century, this universal key just might do the trick for you.
