Click the icon to display the bounding box (the little box with horizontal lines), and then in the Var field, type the name of a variable by which you’ll reference the value of your password.
Don’t confuse this with an instance name; the instance name would be referring to the actual text box itself, but the variable is used to refer to the text entered into the input field. So if I typed “purple monkeys” into the input field, then password=”purple monkeys”.
