Perhaps I do not fully understand your question. The Cisco routers that ship with SDM are configured with a default ID and password that you use the first time that you logon. You can not change that before you logon the first time. When you have logged on you can certainly change it - and in fact I believe that the new version of SDM requires that you change it when logging on the first time.
If this does not satisfy your question then perhaps you can clarify what you need.
