Syntax

passdlg(uitype) It will always produce one masked password field plus the  
       optional components:
         * 'u' or 'UsernameField'
         * 'c' or 'ConfirmPass'
         * 's' or 'ShowHideCheckBox'

       UITYPE can be a cell array with above named fields or a string with
       the initial letters 'u', 'c' and 's', e.g. passdlg('cs').

passdlg(..., Name, Value) For valid Name/Value pairs refer to Figure Properties

passfield(Name, Value) For valid Name/Value pairs refer to the Uicontrol Properties
       plus the following:
         * 'EchoChar'  -   character displayed in field
         * 'Password'  -   plain text string of the password

Warning:

This code heavily relies on undocumented and unsupported Matlab functionality. Use at your own risk!

passdlg();
passdlg('us');
passdlg usc
