Because your Apple Watch is paired with your iPhone, it has access to your contacts, messages, calendars, and more. If your Apple Watch is lost or stolen, your personal data is at risk. It’s essential to turn on the privacy and security settings on your Apple Watch. Here are five crucial security settings on your Apple Watch that you should check right now.

When you first set up your Apple Watch, you’ll be prompted to create a passcode that you can use to unlock the watch, just as you would when setting up an iPhone passcode. This basic security measure prevents someone from taking your device, viewing its contents, and using your Wallet to fund a shopping spree.

To change and strengthen your current Apple Watch passcode, open the Settings app on your Apple Watch and tap Passcode > Change Passcode.

If you have a complex, secure iPhone passcode and want to use your iPhone to unlock your Apple Watch, open the Apple Watch app on your iPhone, tap My Watch, then select your device. Tap Passcode and turn on Unlock with iPhone. You can also open the Settings app on your Apple Watch, tap Passcode, then tap Unlock with iPhone.
