Everywhere you look this week, you see talk about Facebook's "people you may know" algorithms creepy sentience suggesting that patients of a certain psychiatrist friend one another, and of an investment firm that took out a short sale position (basically a bet that the stock would fall in value) in a medical devices firm, then profited when they published news that the firm's devices had serious and easy-to-exploit flaws.
I'm not going to talk about either of those events in this post.
In late July, the US Social Security Administration made a significant change to "my Social Security," the online portal for accessing and managing benefits. In order to improve the security of the site, the government agency began to require two-factor authentication via a code sent by text message. In order to log in, you had to have both your password, as well as a phone to receive the text message on.
