title: Did I delete my RDS master user?
body: <p>We have a MySQL instance running in RDS. A guy that is no longer in the company set that up. As root account, he set <code>thomas</code>. After he left, one of the things I did was, using MySQL Workbench, create another root user and then delete the user <code>thomas</code>. It's been several months since and I've just noticed that the snapshots created automatically by RDS show <code>Master Username: thomas</code>.</p>
  
  <p>It says <a href="https://aws.amazon.com/rds/faqs/" rel="nofollow noreferrer">here</a> that </p>
  
  <blockquote>
    <p>The master user account is a native database user account which you
    can use to connect to your DB Instance</p>
  </blockquote>
  
  <p>From my understanding, that means that it's a normal DB account, the one I deleted when the guy left, and the backups should be failing. But I see no evidence of this, in the Events section it just states "Backup DB instance" and "Finished DB Instance backup".</p>
  
  <p>Can somebody explain what is this master user if not the user I deleted? What's going on with the backups?</p>
