Gets or sets the character to be displayed in substitute for user input.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The password character specified is the same as the current prompt character, PromptChar. The two are required to be different.
For sensitive user input, it is common practice to conceal the actual information entered by the user. If the property is set to a non-null character, MaskedTextBox will display this character for all input into the control. Setting this property to null will disable this functionality.
If you want to use the operating system supplied password character, which is defined in COMCTL32.dll, use the UseSystemPasswordChar property instead. If both the and UseSystemPasswordChar properties are activated, the latter takes precedence.
As a security consideration, the MaskedTextBox control disables cut and copy operations on password-protected strings.
