Apple Watches can easily be factory reset by thieves without the owners' passcodes, staffers at the Apple-centric iDownloadBlog have discovered.

Their method, documented in a YouTube video posted Thursday, involves bringing up the power-off screen, choosing a factory-reset option and then placing the Apple Watch on a charger, which will wipe all user data and settings without the user's passcode.

Once factory reset, the watch is essentially like new and can be paired with any iPhone. Tom's Guide was able to quickly replicate the method.

Apple Watch owners are not required to set a passcode for their devices, unless they intend to use the watch for Apple Pay. If a passcode is set, the user must enter it every time the Apple Watch is removed from the user's wrist, and when it is rebooted.

Apple devices running iOS 7 or iOS 8 are protected by Activation Lock, which makes it nearly impossible to factory-reset an iPhone or iPad without the user's Apple ID password. The feature has been credited with a drop in the rate of iPhone theft in New York, San Francisco and London.

Intricate workarounds to get past an iPhone's lockscreen are often discovered. However, they're often difficult to replicate, at least on the first try.

Apple did not immediately reply to a request for comment. We will update this story if the company comments.
