How to prevent hotmail store password algorithm from breaking in my system?

By chance I came upon a page which gave a detailed instruction on how to use Hotmail store password algorithm to access someone's Hotmail account unauthorizedly.
I have been using Hotmail for about 10 years now and now after reading about this (turns out there are many ways to access somebody's account) I am very worried.
Is there any way I can make my account free from being accessed by anyone without my knowledge?
