This is a companion app for Mac app 'Unlock'.

Unlock intelligently locks and unlocks your Mac and Unlike others, it is incredibly reliable in doing so in day-to-day use and does not require pairing with your iOS device. It's seamless so while using Unlock you never see your Mac locked, while others find it locked.

Setting up smart Unlock is really easy, just keep your iOS device near your Mac and select the device that pops up. We bet you will be amazed how reliable and seamless this can be while being extremely secure. Unlock also makes you more aware about your privacy on Mac. It can notify you if a process is using your camera or microphone.
