API Key and WordPress Username

I have a number of blogs that are on my own hosting with godaddy.com
I am trying to add AKISMET plug-in to stop spam and it is asking me for my API Key.
The problem is to get my API KEY it is making me set up a new user name and account with wordpress different then the one I set up for my blogs through Godaddy.com It will not let me sign in and give me an API Key through that username. So I set up a new username which is this one im using here and it gives me an API Key, bought obviously my blogs are not under this username. How can I go about getting an API Key for all my blogs that use wordpress but are hosted on my godaddy.com server?

Thank you,
