Explanation
The parent ordinal attribute is the index of the parent element among its siblings in the application hierarchy. It can be used to help identify an element that has a dynamic or non-unique class name or ordinal by using its relative position to its parent element1. In this case, the password field has a class name of "Edit" and an ordinal of 1, which are not unique among other elements in the application. However, its parent element has a class name of "Window" and an ordinal of 2, which can be used to distinguish it from other elements with the same class name and ordinal.
