title: Firebase verify multiple email addresses for the same user
body: <p>I'm using Firebase web SDK 4.0.0 and want to enable my users to verify multiple email addresses for the same account. For context, my objective is to receive email from dave@home.com and dave@work.com and know that it's definitely coming from Dave (uid 123456789).</p>
  
  <p>I've looked up the <a href="https://firebase.google.com/docs/auth/web/account-linking#link-email-address-and-password-credentials-to-a-user-account" rel="noreferrer">docs about linking accounts</a> but I'm assuming this approach isn't going to work as I need multiple emails.</p>
  
  <p>I thought about storing the emails in the db and linking them to the user but that doesn't hook into the Firebase verification process (which I want to use).</p>
  
  <p>Any ideas of how to approach this would be very helpful.</p>
