ssh sequence asks for password even when a password is not needed

[manoliskapernaros]

When I run corteca exec install qemu it prompts me to type a password but the ssh server does not require a password. I can press the ENTER key and the sequence continues successfully.

Is it possible to remove the password prompt in this case?

Thanks.
