Set and Strengthen an Apple Watch Passcode

When you first set up your Apple Watch, you'll be prompted to create a passcode to use when unlocking the Watch, just as you would with an iPhone passcode. This basic security measure stops anyone from taking your device, viewing its contents, and using your Wallet to go on a shopping spree.

If you have a complicated and secure iPhone passcode and want to use your iPhone to unlock your Apple Watch, open the Apple Watch app on your iPhone, go to Settings > Passcode, and select Unlock With iPhone. Alternatively, open the Settings app on your Apple Watch, tap Passcode, and then tap Unlock With iPhone.

If you want to change and strengthen your current Apple Watch passcode, open the Settings app on your Apple Watch, tap Passcode, and then tap Change Passcode.

Enable Notification Privacy

It's convenient and easy to check notifications right from your wrist as they arrive on your iPhone, but this may not always be desirable. If you have privacy concerns and would rather not have your notifications pop up in-depth on your Apple Watch, Apple allows you to enable a feature called Notification Privacy.

With Notification Privacy enabled, you can see that you've received a notification, but its details aren't visible until you tap the alert on your Apple Watch.

To turn on Notification Privacy, open the Apple Watch app on your iPhone and tap the My Watch tab. Select Notifications and then toggle on Notification Privacy.

Find My Apple Watch and Activation Lock

If an Apple Watch is lost or stolen, the Find My Apple Watch feature protects you in several ways. It will locate your Apple Watch on a map and then automatically trigger the Activation Lock feature, so no one will be able to open, unpair, or otherwise mess with your Apple Watch without inputting your Apple ID and password.

To make sure Find My Apple Watch is enabled, go to the Apple Watch app on your iPhone, and then select My Watch > [your watch name] > Info. If you see Find My Apple Watch there, it means you're protected by Activation Lock.

When Find My Apple Watch is enabled, you can also turn on Lost Mode, where you can set a custom message that will display on the screen along with a number where you can be reached. If the situation is dire, you can also remotely erase your Apple Watch data.

If you're selling or giving away your Apple Watch, be sure to turn off Activation Lock first.

To turn on Erase Data, open Settings on your Apple Watch, tap Passcode, and then toggle on Erase Data.

If you're concerned about sharing data produced by the Apple Watch's heart rate monitor and fitness tracking features, restrict this information via the Apple Watch app on your iPhone. Go to Privacy > Health, tap Heart Rate, and toggle the switch to off. Toggle off Fitness Tracking to stop sharing this data.

Any of the location services, analytics, contacts, and health settings activated on an iPhone are also activated on every paired Apple Watch. Manage these settings in your Watch app's Privacy section.
