Service Connect User Account can access Epicor (create/update things via SC)?

I want to confirm if Service Connect User Account can access Epicor (create/update things via SC) without using an Epicor user account.

Service Connect uses the Epicor account you set up when you import the .NET references. It will also use a DefaultUser license unless you buy and set Service Connect to use a WebServices license. Additionally, if you set up Service Connect to run multi-threaded, it will use a license per thread.

Thanks a lot.
