EC2 Password Authentication

When you stand up an AWS instance, it’s only accessible via SSH key using the default user, typically ec2-user.

Add password to ec2-user, then enable password authentication to ‘yes’ in SSH.

# Add password to ec2-user
sudo passwd ec2-user
# edit ssh config
vim /etc/ssh/sshd_config
# enable password authentication
PasswordAuthentication yes
# save file and exit

Restart SSH service.

systemctl restart sshd.service
