Northern Trail Outfitters (NTO) wants to import recent customer transaction data from their data warehouse into Marketing Cloud on a nightly basis. They plan to create a File Drop Automation to trigger an automation when a data file is transferred from the data warehouse to the import folder in their Enhanced FTP account. NTO notes that user passwords expire every 90 days and they do not want to update their file transfer script on the data warehouse each time a password changes and they do not want to compromise security. Which solution should the consultant recommend?
