   This is your login username for NASA Earthdata

   .. py:attribute:: password (str,required)

   This is your login password for NASA Earthdata

Notes
-----

1. If the ``url`` contains a ``*`` in its last segment, all files matching the wildcard string will be downloaded. 
   For example, ``https://e4ftl01.cr.usgs.gov/MOTA/MCD15A3H.006/2002.07.16/*`` will result in all files served at 
   this URL to be downloaded.
   If ``url`` were ``https://e4ftl01.cr.usgs.gov/MOTA/MCD15A3H.006/2002.07.16/MCD15A3H.*.h09v07*.hdf``, only files 
   matching the ``MCD15A3H.*.h09v07*.hdf`` pattern will be downloaded.

2. The connector uses simple HTML parsing to determine the list of files matching the wildcard entry. It is assumed that 
   navigating to the base URL i.e. ``https://e4ftl01.cr.usgs.gov/MOTA/MCD15A3H.006/2002.07.16`` above, returns a simple 
   HTML listing of ``<a href=...></a>`` elements. 

3. When using this plugin in a workflow, leave the password binding blank to avoid saving sensitive information to the 
   workflow file. The workflow engine will prompt the user to enter a value securely when executing the workflow.
