Atama has released Sesame2, a Bluetooth Smart keyfob and companion application to lock your Mac or Windows PC. A second generation update of the original Sesame product, Sesame2 boasts an external redesign in addition to further enhancements such as longer battery life, shorter locking distance and increased Bluetooth signal stability.

The device enables users to lock their computers whenever they walk away from the computer, preventing anyone else from accessing files, programs, the email client or anything else that might be open on the desktop. When the user returns to their desk, their Mac or PC is automatically unlocked.

Thanks to the use of Bluetooth low energy technology, Sesame2 locks your Mac or Windows PC without draining your battery, says Eric Ferraz, CEO of Atama. It’s available for pre-order now for US$49 at the Atama website (http://atama.io/sesame2).
