Hey MacYou can unlock a supported Mac with an unlocked Apple Watch on your wrist by enabling Auto Unlock in System Settings. On macOS Ventura or later, look under Touch ID & Password or Login Password for the Apple Watch option. Your Mac and watch need the same Apple Account with two-factor authentication.
If you already wear an Apple Watch, try this built-in option before installing another unlock app. It can help when you return to your Mac, and it supports certain administrator approvals too. You will still need your password for the first login after a restart or logout.
Check your Mac, watch, and account
- Keep Wi-Fi and Bluetooth enabled on both devices.
- Use the same Apple Account on the Mac and watch, with two-factor authentication.
- Set a passcode on the watch and wear it unlocked.
- Check that the Mac and installed software support Auto Unlock.
Apple’s Continuity requirements list supported models and software, including different minimums for unlocking and administrator approvals. On a Mac, you can also hold Option while opening Apple menu → System Information, select Wi-Fi, and look for the Auto Unlock support entry.
That support check is more useful than guessing from whether a Mac has a notch or Touch ID. Auto Unlock is a separate feature.
Enable Apple Watch Auto Unlock
- On your Mac, open System Settings.
- Select Touch ID & Password, or Login Password if that is the label shown for your model.
- Find the Apple Watch section and enable your watch.
- Authenticate or complete any account prompt that appears.
Older macOS versions use System Preferences → Security & Privacy. Apple’s Auto Unlock setup guide covers both settings layouts.
After setup, lock the Mac and wake it while wearing the unlocked watch nearby. Check the result with your normal login method available. If you have just restarted or logged out, sign in with your password before checking a later wake.
Understand the three different tasks
| Task | What to expect |
|---|---|
| Return to a locked or sleeping Mac | Auto Unlock can log you in when the supported setup is ready. |
| First login after turning on, restarting, or logging out | Enter your password manually. |
| A supported administrator-password request | The Mac may offer approval through a double-click of the watch’s side button. |
| Keep an arbitrary app private in an unlocked session | Use that app’s own privacy controls, a separate account, or an appropriate app locker. |
Seeing an Apple Watch approval for one system prompt does not mean every application will ask for your watch before opening. For that problem, start with the app-locking guide.
If your Apple Watch does not unlock the Mac
Sign in manually first. Then check one part of the setup at a time so you can tell which change matters.
- The watch is locked or out of reach: unlock it on your wrist and move close to the Mac.
- The account or wireless setup changed: review the shared Apple Account, two-factor authentication, Wi-Fi, and Bluetooth.
- The option is missing: check the model/software requirements and the support entry in System Information.
- A previously working setup stopped: follow Apple’s suggestion to turn Auto Unlock off, restart the Mac, and enable it again. Save work before restarting.
- Sharing features are active: Apple lists Internet Sharing and Screen Sharing among the settings to check when troubleshooting.
Check for available macOS and watchOS updates too. On a managed Mac, some settings may be controlled by your organization; ask its administrator instead of changing account protections to make a convenience feature work.
If you want to unlock without wearing a watch
Touch ID and your Mac password remain the simplest native choices. A camera-based app is another option if your goal is unlocking when you look at the screen. The Face ID for Mac guide explains why regular-camera recognition differs from Apple Face ID.
Hey Mac adds camera-based lock-screen unlocking and selected-app shielding on Apple silicon with macOS 14 or later. Its setup guide explains the saved-password and permission requirements before you enable it.
If you are comparing phone proximity with a watch or camera, read the BLEUnlock alternatives and Near Lock alternatives. Walk-away locking is a separate requirement to check.
Questions about Apple Watch unlocking
Does taking my watch away automatically lock my Mac?
Do not assume it does. Apple’s Auto Unlock instructions describe unlocking and approving supported requests. Lock your Mac when leaving it, or evaluate a separate departure-locking workflow if that is essential.
Can someone nearby use my already-unlocked Mac?
Auto Unlock does not put a verification step on every action in an open session. Use separate accounts when sharing the computer, and lock the session before leaving it unattended.
Do I need an iPhone app to make Auto Unlock work?
Apple’s built-in Mac unlock setting does not require installing a third-party unlock app. Your watch still needs to be properly set up with its Apple Account and passcode.
