title: Store quiz score in account
body: <p>I have created a database where a user creates an account by entering their email address and password. </p>
  
  <p>I also followed a tutorial where a user completes a quiz and their username and score is stored into a separate database. How can I store the score of the user to the email they registered with on the separate database? Because currently the user account is created at the start of the process and the user account for the quiz are not connected.</p>
