Sparky password issue

[Linuxfan]

Having issues with using a password that I want for sparky. Had Sparky on one of my desktops for years and had no problems. It died and tried to install sparky on another and the password part said "too many letters, too simple", etc.  Why can't I pick whatever password I want. This reminds me of using windows. Their way or nothing. How can I use the password and length that I want on my computer. Never had this issue with any other linux OS. Any help?
