title: How to connect CircleCI and AWS?
body: <p>I'm new to CircleCI, and trying to connect CircleCI - terraform - AWS. </p>
  
  <p>For security reasons, I enforced MFA for aws cli. In other words, I'm using temporal 24-hour lasting: </p>
  
  <ul>
  <li>aws_access_key_id</li>
  <li>aws_secret_access_key</li>
  <li>aws_session_token. </li>
  </ul>
  
  <p>It's quite tricky to apply circleCI in this situation.</p>
  
  <p>What should I do? 
  Should I have to change the above mentioned AWS credentials before every commit? </p>
