Best way to sign into wordpress with webplayer?

I am trying to develop a web player that will allow users to sign in using a wordpress login. If I could let them simply log in using their browser and then let the web player use the same session, that would be ideal. However if I cannot do that, I would love to hear solutions that others have come up with for doing this.

Thank you all in advance!

using Unity’s WWWForm/WWW objects, you can use PHP to communicate with a MySQL database to sign your users in. Thats what I use to log users into my games. If you need a full sample let me know and I will put something simple together to help you learn how it works.
