Step-by-step Guide on How to Lock your Apple Watch for Optimal Security

Table of Contents


The Apple Watch, a popular smartwatch developed by Apple Inc., complements your iPhone, extending its functionality right to your wrist. It serves as a fitness tracker, a way to quickly scan notifications or read messages, a handy tool to answer calls, and even as an electronic key for some cars. But with such valuable data accessible at the flick of a wrist, the importance and usefulness of locking your Apple Watch can’t be overstated.

Why It’s Important to Lock Your Apple Watch

When you lock your Apple Watch, you protect your personal and sensitive data, further enhancing the device’s privacy and security features. The importance of this procedure is threefold.

Security Reasons

Similar to a smartphone, your Apple Watch is a vault of personal data that you wouldn’t want someone else to access. Locking it prevents unauthorized users from accessing sensitive information like messages, emails, health data, or payment information.

Privacy Concerns

When your Apple Watch is unlocked, anyone can see your notifications. By keeping your device locked, you ensure they stay private.

Minimizing Accidental Operations

Locking your Apple Watch ensures that it doesn’t accidentally trigger operations like making a call or sending a message when you are not actively using it.

Different Methods to Lock Your Apple Watch

There are several ways to lock your Apple Watch, ranging from manual to automatic methods, and even locking via a paired iPhone.

Locking it Manually

You can lock your Apple Watch by pressing the side button and then swiping to initiate the lock function.

Automatic Locking when Not in Use

Your watch can automatically lock itself when it’s not on your wrist or when it’s idle for a certain amount of time. To enable this, a passcode must be set.

Using a Passcode to Lock

Create a passcode on your Apple Watch to enhance your security. This passcode will be required each time you wish to unlock your watch.

Locking via the Paired iPhone

If for any reason you can’t lock your Apple Watch manually, you can do so through your paired iPhone.

Step-by-step Guide to Lock Your Apple Watch

Let’s dive into the step-by-step process to lock your Apple Watch manually, set up automatic locking, create a passcode, and lock your watch via your paired iPhone.

How to Lock Manually

Press the side button on your Apple Watch, drag the ‘Lock Device’ slider to the right. Your watch will now be locked.

Setting Up Automatic Locking

To set up automatic locking, open settings on your Apple Watch, tap ‘Passcode’, then toggle on ‘Wrist Detection’. Your Apple Watch will now automatically lock when you’re not wearing it.

Creating and Using a Passcode to Lock

Under the same ‘Passcode’ settings, tap ‘Turn Passcode On’. You will be prompted to enter a passcode.

How to Lock via Paired iPhone

Open the ‘Watch’ app on your iPhone, go to ‘My Watch’ > ‘Passcode’ > ‘Turn Passcode On’. Enter a passcode on your iPhone’s screen.

What to Do if You Forget Your Passcode

Resetting the Passcode

If you forget your passcode, you can reset it using your paired iPhone. In the Watch app, go to ‘My Watch’ > ‘Passcode’ > ‘Reset Passcode’. You’ll need to erase all content and settings from your Apple Watch, which means you’ll also need to pair your watch and iPhone again.

Impact on Your Data and Settings

While this process does not delete any data from your iPhone, it resets your Apple Watch back to factory settings. All personal settings and data will be removed.

Advanced Locking Features

Wrist Detection function

The wrist detection function not only helps with the smart features of your watch, but it also locks your watch automatically when you’re not wearing it.

Unlocking with iPhone

If ‘Unlock with iPhone’ is enabled in settings, you can unlock both your devices at once by unlocking your iPhone.

Activation Lock

Apple’s Activation Lock gives you an additional layer of security. It prevents anyone from accessing or erasing your Apple Watch if it gets lost or stolen.

Tips for Enhancing Apple Watch Security

Regular Firmware Updates

Stay current with Apple’s security updates by regularly updating the firmware of your Apple Watch.

Strong Passcode Selection

Avoid easily guessed passcodes like ‘1234’. Use a more complex passcode for enhanced security.

Disabling Control Centre When Locked

Disable Control Centre access when your watch is locked to prevent access to controlling features like Airplane mode.


Locking your Apple Watch is an important standard practice to maintain the privacy and security of your personal data. Whether you choose to lock it manually, enable the automatic lock or you prefer locking via your paired iPhone, each method ensures your device is secure.
