How to send OTP from a webpage??

Question

I've seen many website which sends OTP and I'm interested to know how to do so from front-end (JavaScript) or from back-end (Python). So, is it possible?

Answer 1

They do from back-end..You can use python, java or any other platform. You can generate random number or you can use your own created costomizes number. Why back-end because you can connect your database with this.

You can store that number in your database and send mail or message to validate OTP on web page.
