Unlock your MacBook Pro with Apple Watch
Use your authenticated Apple Watch to automatically unlock your sleeping MacBook Pro when
you’re close to your computer. Just wake your Mac and start using it—no need to enter a
password. Auto Unlock uses strong encryption to provide secure communication between your
Apple Watch and MacBook Pro.
Note: Auto Unlock is a feature on Macs (mid-2013 and later) running macOS Sierra, and
Apple Watch running watchOS 3.
Set up two-factor authentication for your Apple ID. Auto Unlock works when your Apple ID
has two-factor authentication turned on. Go to Apple menu > System Preferences > iCloud >
Account Details, click Security, then select Set Up Two-Factor Authentication. For more
information, see the Apple Support article
support.apple.com/HT204915 .
Make sure “Disable automatic login” is also selected. (You won’t see this option if you’re using
FileVault, but you can still use the Auto Unlock feature.)
Set up Auto Unlock. Sign in to iCloud with the same Apple ID on all your devices, then click
the System Preferences icon in the Dock, or choose Apple menu > System Preferences. Click
Security & Privacy, then select “Allow your Apple Watch to unlock your Mac.”
Note: Auto Unlock works only when your Apple Watch is authenticated with a passcode. You
authenticate your Apple Watch each time you put it on, so no extra steps are required after you
enter your passcode.
Skip the sign-in. Walk up to your sleeping MacBook Pro wearing your authenticated Apple Watch
on your wrist, and lift the cover or press a key to wake your MacBook Pro—Apple Watch unlocks it
so you can get right to work.
