Locking Your Apple Watch
Enabling the Wrist Detection feature is the best way to make sure your Apple Watch locks when you aren’t looking at it. The original Apple Watch had a manual lock option, but if you’re using watchOS 3.1.3 or later, the manual lock option is no longer available. Apple replaced it with the Wrist Detection feature. The other way to force the lock screen is to turn off your Apple Watch. You must enter your passcode when you turn it back on.
Turning on Wrist Detection
Wrist Detection is handy and easy to activate. You can also turn on Wrist Detection on the Apple Watch itself by tapping the Settings icon on the app screen, followed by Passcode. Move the slider next to Wrist Detection to On/green.
Using Water Lock
Apple Watch with watchOS 5 or later offer water protection. Water can activate your screen, so whether you’re wearing your watch in the shower or going for a swim, the Water Lock feature is handy. Selecting a water activity in the Workout app automatically turns on Water Lock. If you’re not counting your shower as a workout, you need to turn it on in the Control Center.
Set a Passcode With a New Apple Watch
One of the first things you are prompted to do when setting up a new Apple Watch is to create a passcode. You can bypass this step, but it’s a quick way to protect your watch right out of the box.
Adding a Passcode After Initial Pairing
If you opted not to make a passcode when you initially paired your Apple Watch, you can do it later, either on the Apple Watch or on your iPhone using the Apple Watch app.
Adding a Passcode on Apple Watch
You can add a passcode directly on the Apple Watch. You cannot set a longer passcode on your Apple Watch directly. You have to use your iPhone to do that.
Adding an Apple Watch Passcode on iPhone
You can also use your iPhone to turn on the passcode feature for your Apple Watch.
Adding a Longer Passcode on iPhone
If you created a four-digit code initially but want to have a more secure passcode, you can update it through your iPhone. Open the Apple Watch app on your iPhone and select Passcode. Use the toggle switch to turn off Simple Passcode and then the app directs you to your Apple Watch for the next steps. Enter your current four-digit passcode on the watch. Then enter a new, longer option and tap OK. Reenter the code to verify it. Now you’re ready to keep your Apple Watch safe from prying eyes, curious toddlers, and potential water damage.
