Answer 1

The error message is right. WCF will not allow transport of usernames and passwords over an unprotected protocol. Your web service must be using HTTPS (with the attendant SSL certificate)

Once you have an SSL certificate you have two options on how the credentials are sent, transport or security and multiple options for the type of credential. MSDN has a good guide to all of the various options.
