whiptail --password : How does it work?

I have a question regarding "whiptail utility" in Linux.
I have the following whiptail command within a script:

  #!/bin/sh
whiptail --passwordbox " Password " 10 40

I would like to know Where does it store the password when the script is run?

Does it go to any particular file? How does it store the password and where?

Kindly reply,

Thank you
