Are you sure you are using the latest version of the image? It appeared on March 18 (yesterday). One of the changes made to them is the lack of having to enter the password using the HDMI monitor. Nevertheless, look again at my post from 20 January:
You just have to change log session. You can do it by clicking on Ubuntu’s icon and choose another session (password: husarion). It’s necessary to do it only once. We will fix that in the next release of image.
This should solve your problem without having to re-record SD cards.
