Initial setup - what is the default Administrator/root password?

Hello,
I installed the “UCS-KVM-Image.qcow2” image in a new DigitalOcean droplet.
When accessing a login is asked. But I did not enter a password during the import of the image. I dont how what kind of user/password to enter.
The page I’m facing is “Login at unassigned-domain”

Thank
