How to prevent a new user from registering with a previously used Email ID?

Hi Team, I am creating a sign up system and want to prevent user to use the same email address existing in the database while registering. How can I check if the email ID exists in the database before user click the Complete Sign Up Button? Meaning I want to validate the Entered Email ID as soon as its input in the input box.

Thanks so much… any help is greatly appreciated

This should already be possible with the Sign Up workflow.

Email addresses must be unique. This is built in. No need to do anything.

Thank you everyone. I did use the available sign up workflow and it worked like a charm!

That’s good, have fun with rest of the development.
