The property determines whether user-supplied input should be displayed in the MaskedTextBox as multiple occurrences of a password character defined by the operating system. functions similarly to the PasswordChar property, but instead of using a programmer-supplied character for the prompt, uses a prompt defined by the operating system. This property has precedence over PasswordChar.
As a security consideration, the MaskedTextBox control disables cut and copy operations on password-protected strings.
