  • Procedure adapted from https://unix.stackexchange.com/questions/210228/add-a-user-wthout-password-but-with-ssh-and-public-key

    1. create a variable with username

      sudo useradd -m -d /home/$username -s /bin/bash $username
sudo mkdir /home/$username/.ssh
sudo vim /home/$username/.ssh/authorized_keys

      sudo chown -R $username:$username /home/$username/.ssh
sudo chmod 700 /home/$username/.ssh
sudo chmod 600 /home/$username/.ssh/authorized_keys
