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?

    And then there are times you set a password and everything just seems to work fine, but later the new password never works. You reset the password, try again and really focus because you think you made some mistake with the password manager. Again the password you set does not work.

    You begin to google the problem and see that there is a max password lenght of 12. But you always set passwords of the lenght 20-30 and the interface never complained. But because you are desperate, you try just the first 12 characters of the last password you set. And it works!
