You’re sitting in a coffee shop, your MacBook is asleep, and you really don't feel like typing that 14-character password for the tenth time today. Naturally, you glance at your iPhone. It’s right there. It has Face ID. It knows exactly who you are. Why on earth can't you just unlock MacBook with iPhone out of the box?
Honestly, it’s one of those weird Apple "gotchas" that drives people absolutely nuts.
If you own an Apple Watch, you know the magic: you sit down, the Mac senses the watch, and click—you’re in. But for some reason, despite the iPhone being the center of the Apple universe, the company hasn't baked a direct "Face ID to Mac" unlock feature into macOS or iOS yet. It’s frustrating. It feels like a missed opportunity. But just because Apple didn't build a big shiny button for it doesn't mean it’s impossible. You just have to be a little bit craftier than the average user.
The Big Letdown: Why Apple Makes You Wait
Apple is obsessed with "continuity," but they’re also obsessed with selling hardware.
The official stance—if you read between the lines of their security whitepapers—is that the Apple Watch provides a unique "proximity" signal via Bluetooth and the U1/U2 ultra-wideband chip that is consistently "on" the user's body. An iPhone might be on the table, or in a bag, or being held by someone else. Because of that, Apple views the Watch as a more secure biometric tether.
Does that make sense? Sorta. Is it annoying? Totally.
But let's talk about what actually works. If you want to unlock MacBook with iPhone, you're basically looking at three distinct paths: third-party software that bridges the gap, using the iPhone as a security key, or—and this is the one most people overlook—leveraging the iPhone to bypass the password via Remote Desktop or specialized scripts.
Near Lock: The Long-Running Heavyweight
If you’ve spent any time searching for a way to bridge this gap, you’ve probably seen Near Lock.
It’s been around forever. It’s basically the gold standard for this specific niche. The way it works is pretty clever: it uses Bluetooth Low Energy (BLE) to calculate the distance between your phone and your Mac. When you walk away, the Mac locks. When you walk back, it unlocks.
You can set it so that it requires Face ID on the phone before the Mac opens up. This is the closest you will ever get to a native experience.
Setup is usually a breeze, but Bluetooth can be finicky. Sometimes you’re standing right there and the Mac just stares at you. Other times, you’re in the next room and it unlocks because the signal "bled" through the wall. It’s not perfect. It’s a third-party hack, after all. But for many, it’s the only way to get that "Watch-style" convenience without actually buying a $400 watch.
The Security Trade-off
Let's be real for a second. Every time you install a third-party app that has the "authority" to unlock your computer, you’re widening your attack surface. You have to trust the developer. Near Lock is reputable, but you're still giving a middleman app a lot of power over your system’s gatekeeper. If you're working on top-secret government files, maybe stick to the manual password. If you’re just trying to watch YouTube faster? Go for it.
The "Passkey" Revolution is Changing the Game
Things got a lot more interesting recently with the introduction of Passkeys.
While this isn't technically a "wake up the screen and unlock" feature in the traditional sense, it is how most of us will unlock MacBook with iPhone functionality for specific apps and websites in the future. Apple, Google, and Microsoft are all pushing this.
If you’re trying to log into a site on your Mac, your iPhone can act as the physical authenticator. A prompt pops up on your Mac, you scan your face on your iPhone, and boom—you’re logged in.
It’s seamless. It’s secure. It uses the FIDO2 standard.
The problem is that this doesn't solve the "Initial Login" problem. When you first cold-boot your Mac, FileVault encryption is active. At that stage, the OS isn't even fully loaded yet. Bluetooth drivers aren't active. Nothing—not even an Apple Watch—can unlock a Mac on a fresh boot. You must type that password.
Unlocking via Apple Watch (The "Official" Way)
Look, I know you want to use your iPhone. I get it. But we have to acknowledge the elephant in the room: Apple really wants you to buy a Watch.
If you have an Apple Watch, the feature is called Auto Unlock.
- You need two-factor authentication enabled on your Apple ID.
- Both devices need to be signed into the same iCloud account.
- Your Mac needs Wi-Fi and Bluetooth turned on.
You go to System Settings > Touch ID & Password (or Login Password on older Macs) and toggle the switch for your Watch.
It is incredibly reliable compared to any third-party app. It uses "Time of Flight" distance measurement so it won't unlock if you're too far away. It’s the "intended" way to solve this problem. If you find yourself constantly wishing your iPhone could do this, you might actually just be an Apple Watch customer who hasn't pulled the trigger yet.
What About "Unlocking" Apps?
Sometimes people say they want to unlock MacBook with iPhone, but what they actually mean is they want to control their Mac remotely.
Apps like Gateway or Unified Remote let you trigger system events from your phone. You can tell your Mac to sleep, wake up, or even restart from across the room.
I’ve seen some people use Shortcuts for this, too. You can technically create an SSH script in the iOS Shortcuts app that sends a command to your Mac to "caffeinate" it or wake it up. It won't bypass the password screen (because of security "sandboxing"), but it can get the screen glowing and ready for you before you even sit down.
Common Myths and What Doesn't Work
Don't fall for the scams.
You’ll see apps on the App Store promising "Face ID for Mac" that have 2-star ratings and a lot of angry comments. Many of these apps simply don't work anymore because Apple tightened the "Sandboxing" rules in macOS Sonoma and Sequoia.
Apple doesn't allow apps to "inject" a password into the login screen easily. It’s a massive security risk. If an app can type your password, a virus can type your password.
Also, trying to use "AirDrop" as a trigger for unlocking? Doesn't work. Trying to use "Find My" to unlock? Nope. The system is designed to stay locked unless a very specific set of encrypted handshakes happens.

Making it Happen: Actionable Steps
If you are dead-set on making this work today, here is your path forward.
First, check if your Mac actually supports the hardware requirements. You need a Mac from roughly 2013 or later for most BLE (Bluetooth Low Energy) solutions to function.
- The Near Lock Method: Download the app on both your iPhone and your Mac. Follow the pairing process. Start with the "free" version to see if the Bluetooth connection is stable in your specific environment. Walls and 2.4GHz Wi-Fi interference can ruin the experience.
- The Passkey Transition: Ensure you’re running the latest version of iOS and macOS. Start using Passkeys for your Google or Apple account. You’ll start to see how the iPhone acts as a "key" for the Mac, even if it isn't unlocking the desktop itself yet.
- The "BetterTouchTool" Approach: If you’re a power user, look into BetterTouchTool. It allows for crazy levels of automation between iOS and macOS. You can set up "Remote Triggers" where hitting a button on your iPhone screen sends a specific command to your Mac.
The Reality Check
At the end of the day, using an iPhone to unlock a Mac is a workaround.
Apple’s ecosystem is a "walled garden," but some walls are thicker than others. The wall between the iPhone's Face ID and the Mac's login screen is currently built out of heavy-duty security protocols.
If you want a truly seamless experience, the Apple Watch is the answer. If you hate the Watch, the next best thing is a Mac with Touch ID built into the keyboard. Honestly, tapping a finger on a key is faster than pulling a phone out of your pocket, scanning your face, and waiting for a Bluetooth signal to travel through the air.
But hey, the tech exists for a reason. If you’ve got your Mac docked and the lid closed, and you're using an external monitor without a Touch ID keyboard, then an app like Near Lock isn't just a "neat trick"—it’s a legitimate lifesaver.
Next Steps for a Smoother Experience
If you’re going to use your phone as a key, make sure your Bluetooth "Handoff" settings are correctly configured. Go to General > AirPlay & Handoff on your iPhone and make sure everything is toggled on. On the Mac, check the same under System Settings > General > AirDrop & Handoff. Without this "Continuity" backbone, none of these third-party apps stand a chance of working consistently.

Also, consider shortening your "Require password after sleep or screen saver begins" time to "Immediately." If you're going to use an auto-unlock tool, you want the computer to lock the second you walk away, otherwise, the whole setup is just a security hole waiting to be exploited.
The dream of a native "Face ID via iPhone" for the Mac is still just that—a dream. But with the right tools, you can get about 90% of the way there.
