Walking away from your laptop without locking your screen can have some unintended consequences, from the innocuous Facebook status hijack to the much more serious theft of personal information. It’s just good practice to lock it, but it’s easy to become distracted. With the Sesame 2 Wireless Auto-lock Keyfob for Mac, the minute you walk away the screen will lock and it will unlock as soon as you return. It uses Bluetooth 4.0 for low-power consumption, and you can set the distance at which it locks through a related application. Normally $39, it’s $29 with this deal.
