Definition and Usage
The defaultValue property sets or returns the default value of a password field.
Note: The default value is the value specified in the HTML value attribute.

If there are no changes, defaultValue and value is the same (see "More Examples" below).
The defaultValue property is useful when you want to find out whether the contents of a password field have been changed.
