If you have an Apple Watch, you might be pleased to know that it can be used to unlock your MacBook, without the need to enter its Login Password.
This means, you don’t have to go through the annoying process of waking up your device and typing the password, every time you attend a phone call or check papers and find your computer being locked.
This feature on Apple Devices is known as “Auto Unlock” and it was first introduced by Apple way back in 2013, via macOS Sierra update.
