The Output Excel node does not support the creation of password protected Excel files.
You may want to create a request for this functionality on the Precisely Ideas portal as this makes the request visible to the Product Management team and would allow other users to vote for it.
As a work around you could create the Excel file, use the Archive Compress node to create a password protected archive that contained the Excel node and then delete the original Excel file.
