virtual keyboard for log in

I installed Leap 42.1 on my 2-in-1 tablet (VAIO Z Canvas) which has a touch screen and a keyboard. The touch screen works fine with a digital stylus or my finger. I also have virtual keyboard installed so I can use the touch screen once I log on the tablet and open Cinnamon desktop environment. I wonder if there is a way to have the virtual keyboard available for password input ? Thanks.
