What is daw.apple?

Hello, I am a long time apple user and recently noticed a message pop up when I am on my iMac. I don't remember if I'm getting into mail or a web page but I get a box that asks if I will allow daw.apple.com to access my keychain info. What is daw.apple? I have not seen or heard of 'daw' before but maybe something in a recent update has shifted something.

Also, when I goggled this, it took me to my apple id profile and asked me if I want to combine my two apple ID's. I have the one I set up years ago for these discussion forums, long before I had an account in itunes, etc. When I got my first iphone, they asked me if I had an apple id. I said, well, I''m not sure, and they asked me what I used for itunes. I said I had not bought anything through itunes so they had me set up a 'new' apple id. so now I have two. I don't mind but, I know which one is for purchases and which is for my discussion history. I am happy to keep them seperate but wonder if there is a reason to combine them.

Thanks for your help.
