Introduction

In today's fast-paced digital world, user authentication is a critical aspect of web applications. With traditional login methods requiring users to remember passwords or go through the hassle of mobile OTPs, a more efficient and secure solution is needed. OTPLESS offers a groundbreaking one-tap sign-in experience using WhatsApp, revolutionizing user authentication. In this blog, we'll guide you through the steps of integrating OTPLESS into your React application, enhancing user experience and data security.

Step 1: Install the OTPLESS SDK

To get started, install the OTPLESS SDK in your React application by adding the following script to your login page:
html
<script type="text/javascript" src="<https://otpless.com/auth.js>"></script>
Upon successful installation, the OTPLESS widget will be visible on your login page, ready to provide a hassle-free sign-in experience.

Step 2: Retrieving User's Information

Once the user successfully authenticates, the user object is returned to you. Implement the following script using the useEffect hook to retrieve and log the user's information:
javascript
import React, { useEffect } from 'react'; const Login = () => { useEffect(() => { window.otpless = (otplessUser) => { alert(JSON.stringify(otplessUser)); }; }, []); // Your login logic here // ... };

Step 3: User Registration and Authentication/Completing the Authentication Process

After the user successfully authenticates, their information will be logged in the console as follows:
json
{ "token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx", "timestamp": "YYYY-MM-DD HH:MM:SS", "timezone": "+XX:XX", "mobile": { "name": "User Name", "number": "User Mobile Number" }, "email": { "name": "User Name", "email": "User Email" } }
Utilize the user details obtained from the previous step to authenticate the user in accordance with your application's specific business logic. You can create a new user account (sign up) or verify an existing user (sign in) based on this information. By implementing OTPLESS, you not only simplify the authentication process but also enhance the overall user experience, building trust and engagement with your audience.

Conclusion

Integrating OTPLESS into your React application streamlines user authentication while ensuring top-notch security and a seamless user experience. With one-tap sign-in using WhatsApp, you can bid farewell to complex passwords and OTPs, offering your users a smoother and more delightful login process.
By taking advantage of OTPLESS, you open the door to increased user engagement and trust, creating lasting relationships with your audience. So, why wait? Get started with OTPLESS today and elevate your React application's user authentication to a new level of simplicity and security. Happy coding!
