I changed my Apple ID password so many times

doesnt matter How many times I change my Apple ID, every time I’m told to put my password in the new passwords I make never work. Right now I’m trying to sign onto my game center account so I can play a game with my son and it keeps Telling me that my pass word is wrong. I have reserved it so many times now. What do I do? Because resetting it doesn’t seem to work so it must be a problem on Apple’s side of things.
