If you own an Apple Watch, you can unlock your Mac without having to type in a password.
Just sit down at your computer and, boom, it’ll unlock itself.
It’s a feature Apple has been offering nearly a year, but it’s one that I hadn’t ever used. I recently picked up one of Apple’s new MacBooks, however, and instantly fell in love with the option. It’s super easy to set up yourself.
Tap the Apple Logo at the top-right of your screen and select “System Preferences.” Then tap the Security & Privacy icon
Check the box that says “Allow your Watch to unlock your Mac”
Enter your computer’s password
That’s all there is to it!
Now, when your Mac is locked and you’re nearby running watchOS 3 or newer (you almost certainly are if you’ve updated your Apple Watch in the last year), the watch will unlock your Mac for you.
