How to automatically unlock your Mac with your Apple Watch

Part of the appeal of the Apple ecosystem is how great devices within it work together. Using one of the best iPhones or a great Mac works well, but they're better when paired with each other. For example, it's possible to unlock your Mac by simply wearing your unlocked Apple Watch, saving you time and preserving your security. Some Mac computers ship with biometric authentication, like the M2 MacBook Air or the Mac Studio, but not all models do. That means for many Mac users, the quickest way to unlock their computer will be with an Apple Watch.
