I created a Ubuntu 18.04 Instance in AWS, then I connected to the instance using the pem file using ssh -i pemfile ubuntu@public-IP
sudo passwd ubuntu Changing password for user ubuntu. New password: Retype new password:
I set the password for the account, then enable the password authentication in the SSH config file
sudo nano /etc/ssh/sshd_config Find the PasswordAuthentication no and set it to yes
sudo service ssh restart
