How to use Auto Unlock
Auto Unlock gives you instant access to your Mac computers when wearing your Apple Watch. Just wake up your Mac and you’re ready to go—without typing a password.
The first time you log in after you turn on, restart, or log out of your Mac, log in by entering your password manually. After that, Apple Watch logs in for you.
Auto Unlock works when you're wearing your unlocked watch and are very close to your Mac. If necessary, move your watch a little closer.
