Now they can be in your neighborhood, using a list of popped accounts to unlock a batch of houses. They can look at your Amazon connected camera to know when you have left your home or children unattended. Amazon accounts get popped all the time.
Amazon is also a great place to get GB/TB of customer data from public S3 buckets.
Some custom built homes intentionally have multiple windows that are too slim for a human to fit through for this reason.
[ Special Note: ] If you decide to do this, ensure you build other methods of escape for fire hazards.
There is a public perception of these super-smart techno hackers that crack all of these damn gizmos and rob you blind, but the reality is that most all B&E is done by dumbass drug addicts who barely make anything on a haul and get caught quickly. Even the more sophisticated ones use basically the same tactics but also make sure to move to a different county every couple of houses to avoid sitting in a jurisdiction for too long.
It's a high risk low reward game. Only the most desperate play it. Someone smart enough to hack the system is smart enough to have many better ways of making money. Even if someone sells a kit for dummies to do this it's still more work than picking up a rock.
Or put a quick kick to the door. The idea that a hollow door with a inch of metal hanging onto the frame is going to stop someone is laughable. Most homes aren't secure.
And while we're at it, the package being left on your porch is not inherent to packages getting stolen or not containing what they should. Heck, ordering stuff isn't even the only way to buy things. So why prevent against it by giving Amazon access to your house, of all things out of all the possibilities there are? The decision to be made isn't between having windows or an Amazon lock, those things are orthogonal. You're adding a shitty additional link to an already weak chain.
Now any random person can break your window with you knowing, any random person can kick the door in with you knowing, and -- I'll pretend to not see the moved goalposts because as I said, no counter-argument is required to a non-argument anyway -- a skilled lockpicker can let themselves in without you knowing. Now, thanks to this amazing technology and given enough time, a script kiddie, not to mention hardened cyberwebs criminals, might be able let anyone in without you knowing or without even knowing the completely unskilled person they let in. That is to say, now even people who wouldn't be able to kick in a door, break a window, or pick a lock can potentially get into your house. And for what? So you can order at Amazon. It's not even a standard to be used for any delivery you want to use it for, just Amazon. This doesn't need an counter-argument. If you want to buy this, you have my blessing.
