Unlock your Mac with your Apple Watch

While you're wearing Apple Watch, your Mac can sense when you're nearby and log you in automatically. You can also use Apple Watch to approve other requests for your administrator password.

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.

How to log in with Apple Watch

The first time you log in after you've turned on, restarted or logged out of your Mac, you must enter your password manually. After that, Apple Watch will log in for you. Just wake up your Mac when you're wearing your Apple Watch and you're logged in automatically – without typing a password.

How to approve password requests with Apple Watch

You can also use your Apple Watch to approve other requests to enter your administrator password. This works any time you need to type your Mac password, such as when viewing passwords in Safari settings, unlocking a locked note or approving installation of an app.

When your Mac asks you to approve with your Apple Watch or enter your password, just double-click the side button on your Apple Watch. Your password will be entered automatically without having to type it.
