DestP[assword] Password

Optional. Allows the storage of a package that is protected by SQL Server 
Authentication. This option is used in conjunction with the DestUser option and
when the destination of an operation is SQL. However, you can use the 
DestPassword option only if you use the DestUser option. If the DestPassword 
option is omitted and the DestUser option is used, a blank password is used.

* Security Note: When possible, use Windows Authentication.
