It’s strong enough to hold up to anything except fairly large bolt cutters wielded by someone with enough strength to squeeze through a quarter-inch of hardened steel, or an angle grinder. You can rest assured that your fingerprint padlock is just as secure, if not even more so, than a standard padlock. As it unlocks with your fingerprint, it is actually more secure than other options, since you can’t lose your key or risk somebody getting hold of your combination code.
It’s important to remember that no lock is fully secure, the question isn’t about whether it can be broken, it’s more about how easy or how long does it take to break and how much of a deterrent is it?
