I used to maintain the directory of userids on a bunch of mainframes when passwords were not encrypted. What always shocked me was how trivial passwords were. Every winter, there would be lots of passwords of “winter”. When Major League Baseball started, there were lots of passwords like “Bluejays” or “Yankees”. Anyone intent on hacking into these accounts could have. (Part of our job was to prevent people from doing just that.)
Flash forward decades later, and it still seems that Simple Passwords Remain Popular, Despite Risk of Hacking according to the NYTimes.com. And what is one of the common passwords? “123456”. Really!
