title: Airflow connections and short-lived passwords
body: <p>One of the problem we have when implementing airflow is that most of our connections seem to be a challenge for it. </p>
  
  <p>After somewhat solving connection over SSH, I am now facing the issue of short-lived passwords: a few of our connection requires password to be asked to another service. These passwords always expire after 1h and the only way to get a new one is to query an internal tool using the command line.</p>
  
  <p>Any idea of how I could solve this issue?</p>
