If you have an Apple Watch, you can use it to quickly and easily unlock your Mac machine. Apple has added a feature to the Watch that lets you unlock your Mac without entering a password. You just need to bring your Watch close to your Mac and your Mac will let you in.

You need to set this feature up on your Mac before using it. Also, there are specific requirements that your devices must meet before you can unlock your Mac with an Apple Watch (Amazon, Best Buy).
