What is Tigergraph password for authentication

never mind. please delete this post

I installed VirtualBox and want to share folders with my pc to copy over some data files to import. I found these instructions here:

  1. Boot the guest OS.
  2. Once booted, click Devices | Insert Guest Additions CD Image.
  3. When prompted, click Run.
  4. Type your user password and click Authenticate.
  5. Allow the installation to complete.

At #4 I get this prompt.


Everything here is from the VB and TigerGraph image installation. where do I get the password for this? of is there another way to copy data files from my pc to the VB machine?
