How to Automatically Lock and Unlock a Mac With an iPhone

Keeping a mobile device secure is something many worry about. But if you an iPhone or iPad, the security of any Mac can be increased when paired with the Keycard app.

The way that the Keycard app works is that the iPhone or iPad is connected to the Mac computer over Bluetooth. When the user walks away from their computer with their device in hand, the screen of the mac locks automatically.

This is a great help for those who work out of coffee shops, or just use their Mac in public places often. The automatic screen locking provides an additional barrier to thieves who may be looking to steal information off a users laptop. It may not keep them from stealing the laptop, but Keycard provides a good step toward keeping your information private.
