It is paramount that you give the account details directly to me while the Bitcoins are in escrow. Without a third party knowing the details.
This is going to make it difficult for the escrow to mediate any disputes between you and the seller. There would be nothing to stop you from claiming that you received credentials that were not valid and there would be nothing to stop a seller from sending you bogus credentials that are not valid, and the escrow would not have any way of knowing for sure who is telling the truth.
