Clicking on the Modify Password link should give you a screen that looks similiar to:
Enter your current password where it says Old Password. Enter whatever you want your new password to be in both of the textbox underneath it. These password must match or the password will not be changed. Also note, the new password will need to be atleast 5 characters. The script runs a quick check on the new password and determines if the password is a dictionary word. If it concludes that it is, it will not change the password and will tell you so. Because of this it is best to use a combination of numbers and letters for your password.
After sucessfully changing your password, you should see a screen similiar to:
Your password has now been changed. When you try to click another link in your Control Panel, you will be prompted to reenter your login information. Your username will stay the same, but you will need to enter your new password in order to navigate your Control Panel.
