title: Multiple users connecting to AWS EC2 via SSH
body: <p>I was trying to organize how a developer could connect via SSH to an AWS instance that I had launched as an administrator. I notice in the documentation that it says:</p>
  
  <p>you'll need the fully-qualified path of the .pem file for the key pair that you specified when you launched the instance.</p>
  
  <p>Does this mean one can only SSH into an instance that one had launched ? I'd like to just leave the instance running and have others able to SSH in to install software and configure.</p>
