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.
The difference between the defaultValue and value property, is that defaultValue contains the default/initial password of the password field, while value is the current password of the password field after some changes have been made. 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.
Browser Support
The defaultValue property is supported in all major browsers.
Syntax
Return the defaultValue property:
passwordObject.defaultValue

passwordObject.defaultValue=value
