SQL Server Authentication without Saving User Credentials

You can improve security for an Access/SQL Server application by not saving user credentials in the linked tables' connection strings. You'll learn how to create a cached connection that Access can use to connect to the linked tables. The user need not see or know their UserID and PWD.
The method demonstrated, however, does not guarantee security against a determined hacker who knows how to get around it. It's "more secure", but never "totally secure".
