Keep your password safe, secure

Today, with web 2.0, you can do many things online such as: email, create document, work group, chat, read news, watch film, sell and buy, archive, forum, blog, share... Usually, every service require user have to create a account with user name and password. It 's very dangerous to use the same password and/or user name for all services. If someone can break into one service of you, he can login all others.
