Simply put Sesame in your pocket and walk away. Once you are out of range, your Mac will lock and nobody will be able to access your sensitive files.
When you come back, the Mac Sesame app will sense the Sesame key fob and unlock your screen, ready for you to continue your work.
Decide how you want to unlock your Mac, be it when you come back within range or still needing a password, it's your choice.
Sesame supports auto-mute and auto-pause iTunes when leaving your Mac. Simply walk away with the knowledge that your Mac will stay quiet.
Sesame communicates with your Mac using Bluetooth 4.0. The key fob will run several months on a coin cell battery, which is easily replaced. It also puts less strain on your MacBook's battery if you are a mobile user.
The Sesame Mac app gives you full control over the locking and unlocking behaviour. The app lets you adjust the disconnection link strength so you can easily decide at what point your Mac should lock.
For those of us who are very security minded, Sesame offers 2-factor authentication. When enabled, you must enter your system password and press Sesame's hardware button to regain access to your Mac.
