Atama has announced Sesame, a Bluetooth keyfob and companion application to secure your Mac. It lets you secure your Mac by starting the system screensaver whenever you walk away, using the small Bluetooth 4.0 keyfob in your pocket

This prevents anyone else from accessing files, Facebook and Twitter accounts, e-mail clients, and anything else that might be open. When you return to your desk, Sesame automatically unlocks the Mac.

It also supports Two-factor authentication — the combination of something the user knows with something the user has). This enables the unlocking of a Mac only through the combination of a button press and the system password.

Sesame is available for pre-order now for US$39.99 and will ship in  late November. For more info go to .
