VMS OS from DEC had exactly the "unique password" stupidity in the late 80s. In a way, it was much worse than Twitter's, because where I worked there were only about a 100 accounts, so you could find the other by hand in less than an hour.

Is it really worse than Twitter's? The image has the website telling you exactly which account is already using that password (it's actually a joke from reddit).

It's interesting to know that this was actually a thing though...
