I strongly recommend installing ssh keys while creating the new user account. You must have RSA/ed25519 key pair on your local desktop/laptop. Use the cat command to view your current RSA/ed25519 public key on the desktop:
$ cat ~/.ssh/id_ed25519.pub $ cat ~/.ssh/id_rsa.pub
Run the following commands on your Ubuntu server to install above ~/.ssh/id_ed25519.pub key from your desktop:
$ sudo mkdir /home/vivek/.ssh/ $ sudo chmod 0700 /home/vivek/.ssh/ $ sudo -- sh -c 'echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILaLvLmaW9qIbUVo1aDHWZE9JewbNfIdTVif2aFGF0E0 vivek@nixcraft' > /home/vivek/.ssh/authorized_keys' $ sudo chown -R vivek:vivek /home/vivek/.ssh/

$ ssh vivek@your-aws-server-ip-here
