Is there a way to know that a user clicked on the verification link?

Question

Here\'s the code I\'m using to send a verification email (taken from the official docs)

var user = firebase.auth().currentUser;

user.sendEmailVerification().the         


        

Answer 1

You can add a continueUrl when sending an email verification to redirect back to your app: https://firebase.google.com/docs/auth/web/passing-state-in-email-actions

var actionCodeSettings = {
  url: 'https://www.example.com/?email=' + 
       firebase.auth().currentUser.email
};
firebase.auth().currentUser.sendEmailVerification(actionCodeSettings)
  .then(function() {
    // Verification email sent.
  });

This will show a continue button after verification. You can use it to go back to the app or to some page where you can notify the original page via real time database of the verification.
