Enable Root account and Password Login on AWS EC2 and Google VM Instances

Amazon EC2 instances and Google VM instances come with root account disabled by default. They also use a PEM key file to authenticate the user so the use of passwords are also disabled. While these are excellent practices in terms of security. Some people prefer to have these disabled for many reasons. Let’s enable root account on AWS EC2 and Google VM instances

This is an optional step. You’ll be able to login to Virtualmin without making changes explained in this tutorial. But you need to set a password for root account first. Following command will guide you through it.

passwd

However, you’ll still have to use key file to login to EC2/VM instance with SSH. You can follow this tutorial if you prefer password logins. And want to login to server as the root user.

Please note that these instructions are for Ubuntu 16.04 instances. But it should work on other Ubuntu versions as well.

Login to your EC2 instance with standard user account. This could be ubuntu or ec2-user depending on the AMI you deployed on your instance. Once inside, switch to root account by executing this command.

sudo -i

Now open the SSH configuration file with nano text editor.

nano /etc/ssh/sshd_config

Search for following line within the file (Ctrl+W),

PermitRootLogin

Now change PermitRootLogin to yes. File should look like this after the change.

Root account will be enabled on your instance after SSH service restart. But you still can’t login to root account because you don’t have password logins enabled on your server. You can enable it by following below instructions.
