Why do so many companies and people say that your password has to be so long and complicated, just to have restrictions?

I am in the process of changing some passwords (I have peen pwnd and it’s the password I use for use-less-er sites) and suddenly they say “password may contain a maximum of 15 characters“… I mean, 15 is long but it’s nothing for a password manager.

And then there’s the problem with special characters like äàáâæãåā ñ ī o ė ß ÿ ç just to name a few, or some even won’t let you type a [space] in them. Why is that? Is it bad programming? Or just a symptom of copy-pasta?

    Centuries? With that much entropy it would take several universe heat deaths even assuming millions of guesses per second I believe.

      Once it gets that long it’s something like if every atom in the universe was used as a bit of computing it would still take some absurd n in 10^n heat deaths. Wild how fast the entropy zooms off the edge of the map
