How to change my Apple ID password

I am going to refer you to this post --> How to change my Apple ID password - Apple Community

If it looks like it isn't taking you anywhere it is because it is only 2 posts above yours in the same thread and was posted last year. It always helps to read other posts before asking the question a third time.
