Hi Cesar and welcome,

"Falha de autenticação" seems to mean "Authentication Failure", you simply
need to pass the right authentication credentials, I suggest you to install
your public SSH key in the authorized_keys file of the user you are trying
to log in, for example, is the user is "cesar", you should put your public
SSH key (which is a text string) in /home/cesar/.ssh/authorized_keys ; once
you do that you should be able to log in without entering any password, eg:

ansible-playbook -i hosts playbook.yml -b -k -K --become-method=su -u cesar
(where cesar is the name of the user).

What's the full ansible-playbook command you're using?

Federico
