Hi, @Fadi-hanna! Thanks for reaching out in our Community Forums and for sharing your concern, I’d be happy to help.
You mentioned that you are looking for an app that allows you to verify your customers via email OTP. Please feel free to provide more details about your requirements, and I can offer a more tailored recommendation.
If you are specifically looking for this functionality during the account creation process, Shopify offers a native feature called New Customer Accounts. When a customer creates an account and enters their email address, they receive an email containing a one-time, 6-digit code that they need to enter in order to log in. You can learn more about setting up this feature here.
Let me know how this information helps, and if there's anything else I can assist you with!

This is not quite true OTP functionality to allow logging in to their account, but with the Helium Customer Fields app, you can require email verification during the actual registration process to ensure that legitimate email addresses are used and that the user actually has access to that email account.
