As you probably know, iPhones and iPads come with the Activation Lock option which prevents thieves from wiping and using a stolen Apple device with a new account. However, as iDownloadBlog website has discovered, the Apple Watch doesn't have this much-needed security feature, thus making it an easy target for thieves,
The Apple Watch has a passcode option that requires a sequence of numbers to be entered every time it's removed from a wrist, but as it turns out, the passcode protects only data. Thus, once a thief gets hold of an Apple watch, he can easily bypass the passcode with a reset.
He can do so by pressing down on the side button of the Apple Watch which brings up the power down options and then perform a force press on this screen to bring up an option to Erase All content and Settings. Have a look at the video from below to see how this can be done:
Furthermore, the Apple Watch is reliant on the iPhone, so there's also no Find My iPhone option to locate a lost or stolen Apple Watch. Apple needs to act fast and introduce stricter security measures in a future version of Watch OS. Who knows, maybe we could see this happen at the upcoming WWDC from next month.
