title: How to use Firebase email address verification
body: <p>There appears to be an option to confirm email address in Firebase Web SDK3, see <a href="https://console.firebase.google.com/project/your-project/authentication/emails" rel="nofollow">here</a> (put your own project id in the link), but I can't find documentation for how to use it.</p>
  
  <p>Anybody done it? </p>
