Ubuntu cloud image OVA in Virtualbox

Ubuntu Cloud Images now provides a downloadable .ova dedicated to VMWare/Virtualbox. While these images are easily importable into Virtualbox I’m struggling to set up a valid users account on the actual system.

All resources I found on the internet are referring to .img files you can download from Ubuntu Cloud Images repository.

How can I gain access to the focal-server-cloudimg-amd64.ova I download from Ubuntu Cloud Images? Is there a default password? Cloud init? Anything else?
