Access EC2 without pem file with with username and password — boobo94

Sometimes you need to grant permissions to someone else and maybe you don’t want to share the .pem file. By default, the ssh access is granted through a .pem file by Amazon EC2.

$ ssh -i pem_file.pem ubuntu@ec2-________.compute-1.amazonaws.com

2. Create a new user

$ sudo useradd -s /bin/bash -m -d /home/USERNAME -g root USERNAME

3. Add a password

$ sudo passwd USERNAME

4. Add users to sudoers

$ sudo visudo

Here you need to add the following line

USERNAME ALL=(ALL:ALL) ALL

5. Enable the access by password through ssh

$ vi /etc/ssh/sshd_config

Here you need to search PasswordAuthentication from no to yes.

6. Restart ssh

$ sudo /etc/init.d/ssh restart

7. Connect to the server using the new user

$ ssh USERNAME@ec2-________.compute-1.amazonaws.com

This is all.
