Proposed article introduction

An OTP generator is a simple one-time password generator and can be used as a password generator. OTP is a password that is valid for only one login session or transaction on a computer system or other digital device. The use of OTP helps to avoid many disadvantages that are associated with traditional (static) password-based authentication. In simple terms, a service accepting OTPs requires a user to select a preferred OTP generator to deliver this dynamic password.

In this guide, the reader will learn how to set them using a React.js application. The reader will first create a Node.js Restful API that connects to the Twillio API. Then create a React app that Sends authentication SMS messages. This SMS will be used to Handle authentication inside the React.js application.

Thank you for submitting your topic @Rose-stack.

However, after some careful consideration, it struck us that this topic may be a bit over-saturated throughout other blog sites and official documentation.

We typically refrain from publishing content that is covered widely on the net or other blogs. As we're more interested in original, practitioner-focused content that takes a deeper dive into programming-centric concepts.
