Your Mac is most vulnerable when you walk away, leaving it unattended. That’s less of a problem for a Mac at home, but definitely an issue for Macs in the office. Whether it’s a meeting, a lunch break, or a bathroom break, walking away from your Mac and leaving it unlocked, unattended, is an invitation for a disaster.
Fortunately, there are dozens of ways to secure your Mac while you step away for a few minutes, up to and including just using a screensaver with a login password.
Or, you could get all high tech on your bad self and use Sesame.
Sesame is a free Mac app and a not-so-free keychain dongle, a wireless key fob that communicates your proximity to the Mac.
Sesame’s key fob uses Bluetooth 4.0 which is the Low Energy version, so it won’t run down your Mac’s battery, and the fob’s battery can last for months. That means you need a more recent Mac to get Sesame and the fob to work.
Set the range you want using the Sesame app. When you walk beyond that range, your Mac will sense that and lock itself up by launching the Mac’s screensaver. You can also use a two factor authentication system for added security.
Why bother with an app and a wireless fob when you can set the Mac’s screensaver to activate to a few minutes? In one minute you could be completely out of site, and in the interim anyone nearby can still get into your Mac. Some companies actually require such security. Besides, there are times when a short activation period opens the screensaver and locks the Mac while you’re sitting in front of the screen.
If you have an iPhone and carry it with you wherever you go, there’s an inexpensive iPhone app called Knock which does the same thing. It uses low energy Bluetooth on your phone to ensure your Mac is locked when you walk away.
Knock is named Knock for a reason. When you come back to your Mac it’s locked up, of course. So, just ‘knock’ on your iPhone twice, even while it’s in the pocket, and your Mac unlocks.
