比如说，你想改变你的应用程序只用用户名登录的想法(这始于用户故事1)，转而使用用户名和口令登录。
Say for example, you want to change the concept of login in your application from just using username (which was where you started at in story 1), to username and password.
注意：你需要改变用户名和口令以适应你MySQL帐号。
Note that you'll need to change the username and password to the appropriate values for your MySQL account.
打上勾，应用改变，输入你的口令，最后点击关闭。
Check the box, Apply Changes, put in your password, and click close.
