Including capital letters, numbers and symbols into your passwords can really strengthen your system’s security and help prevent ‘getting hacked’. The trouble with creating a really secure password is that, often, it’s hard to remember what that password is.
Unthethered Labs LLC has created a product called GateKeeper. GateKeeper is a small wireless transmitter that you put on your keychain. It connects with a USB based receiver on your computer. When you come within a preset distance from your computer (the distance is user-configurable), the computer recognizes your keychain transmitter and unlocks your computer for you.
There is a small piece of software that you install on your computer that allows you to change certain settings, including unlock distance. This is also where you input your computer’s logon password, so your software knows how to automatically unlock your computer when you get close enough.
The keychain transmitter runs on a single CR2032 coin cell battery, and the device comes with a spare battery. I’ve personally been using my GateKeeper for over 6 months, every single day, and I’m still on the first battery. I have tested the device on both domain and non-domain user accounts on Windows 7, 8 and 8.1 (the manufacturer boasts its compatibility with Mac as well). While I have run into situations when my computer randomly locked and unlocked on me for no reason (I’m assuming something interfered with the keychain transmitter’s signal), this is very infrequent and could be more attributed to the amount of wireless signals in my particular office (I’m a third party IT services provider, so I have dozens of WiFi routers going at any point in time). Overall, I have been very, very happy with the product and have recommended it to clients, some of whom are now using it in their own production environments.
