Geoffrey Fowler reviews tech issues for The Washington Post (geoffrey.fowler@washpost.com). I regularly read his columns because he provides insightful expertise. He’s written a column about the Amazon Key that I urge everyone to read (“Amazon wants a key to your house. I did it. I regretted it”; Sunday, December 10; page 1, Business).

Mr. Fowler’s first-hand  assessment is very objective notwithstanding that Jeff Bezos owns The Washington Post and is also Amazon’s Chief Executive.

His cautionary tale is important for anyone considering buying the $250.00 Amazon Key that allows Amazon delivery personnel access, via an Internet-connected lock, to Amazon Key users. Sounds like a good anti-theft device, right? As Mr. Fowler writes, that initial appeal pales in comparison to the reality that using the Amazon Key means giving Amazon  the ability to become the operating system for the user’s entire house.

Mr. Fowler provides details about using the Amazon Key, his reactions and those of his family and — ultimately — their decision to stop using Amazon Key.
