tilqicom's answer will allow you to reset the password to "cabbage", and your initial login name is 'admin' so that should take care of this. Another thing you could do is to tell it your username is admin and click on "lost password".

Oh but to answer the actual question: the initial password is randomly generated, so no one can ever tell you what it was. It was displayed on the bottom of the screen after the installer did it's thing. There is a link at the top that takes you to the blog, but then you will never see the info at the bottom of the screen. It happens from time to time - someone clicks without scrolling to see if there is any other info they might need later. Like a password ;)

Hope it helps!
