Enable software keyboard on login sceen?

I stream a lot of games from my gaming pc running Windows 10 to my Nvidia Shield. I usually lock and put my pc to sleep after a gaming session. The issue is that next time I want to game, I have to sign in on my pc using my controller. Its quite annoying controlling the mouse pointer with my controller, getting up the on screen keyboard and type it. Therefore I am looking for a way to automatically bring up the on screen keyboard (or touch keyboard) at the login/lock screen of windows. Apparently there are settings for this and I have tried them but they do not seem to do anything:

So is there a way to do this? Seems trivial and weird that there is not a way to get this working easily? If it is not possible to do, is there a way to make the accessibility options on the lock screen bigger?
