Yeah, just came up recently when I was trying to help a customer reset their password. They swore that they tried every convoluted password they could think of, but it wasn’t accepting any of them, then I finally sent this message:
The common word library is very large, and the password must be at least twice the length of that common word if it is contained within. For example, Password783! wouldn’t work, but Password78345612! would work since the bold part (not-common) is longer than the italicized part (common).
And of course, he responded with this:
Well, now I have a convoluted password I’ll never remember lol.
Password restrictions have gotten out of control.
