I cannot log in as user pi on my installation of HassBian

okay so I installed hassbian and everything is going fine. I get putty set up, and everything is working, but when I tried to log in to my pi as the user ‘pi’, it asked me for the password. I typed in ‘raspberry’, but it said that raspberry was incorrect! I knew I didn’t spell it, so then I decided to check out the raspi-config file to see if maybe I hadn’t allowed ssh to my pi account, but when I did a quick ls into /usr/bin (where raspi-config should be), it didn’t even list raspi-config on the list!

I’m so confused because that probably means that I messed something up, but i’m sure I didn’t!

So now I cant set up anything because you need access to the user pi ;(
