NASA is eliminating the use of the FTP protocol for any external communications and replacing it with other file transport mechanisms (e.g., SFTP, https).  The timeframe for migrations varies per service.  In most cases, users of the new file transport mechanisms will be required to obtain an Earthdata Login account.  Instructions to register for an Earthdata Login account are available at https://urs.earthdata.nasa.gov/users/new.
