I am using this code but I cannot get current characters.

            case 'backspace'
                password = password(1:end-1); 
                SizePass = size(password); 
                if SizePass(2) > 0
                    asterisk(1,1:SizePass(2)) = '•';
                    set(edit2,'String',asterisk) 
                else
                    set(edit2,'String','')
                end
                set(edit2,'Userdata',password) 
            case 'escape'
            case 'insert'
            case 'delete'
            case 'home'
            case 'pageup'
            case 'pagedown'
            case 'end'
            case 'rightarrow'
            case 'downarrow'
            case 'leftarrow'
            case 'uparrow'
            case 'shift'
            case 'return'
                pus1_callback(varargin);
            case 'alt'
            case 'control'
            case 'windows'
            otherwise
                password = [password get(fig,'currentcharacter')];
                SizePass = size(password); 
                if SizePass(2) > 0
                    asterisk(1:SizePass(2)) = '*'; 
                    set(edit2,'string',asterisk) 
                else
                    set(edit2,'String','');
                end
                set(edit2,'Userdata',password) ;
        end
    end

I don't believe this is possible. What you can do is making a text field that looks like an edit field, and then use this code.

BTW, this code will probably break if the users presses backspace more than there are chars in the current stored password.

Yes there are many problems in this that I cannot handle. Is there any other solution or some builtin functions for hiding my password. Kindly share if possible thanks.

You find many many many solutions for password dialogs in the FileExchange. Simply search for the keyword "password":
