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.

Harness the power of OTPLESS with your React applications to streamline user authentication. This SDK is designed to integrate seamlessly with React, offering both pre-built components and headless functionality for custom UI implementations.

Pre-Built UI

Leverage our Pre-Built UI for rapid integration and customization of authentication flows in your application. This setup allows you to adjust appearance and functionality through the OTPLESS dashboard with minimal coding.

Step 1: Install the OTPLESS SDK

To integrate the OTPLESS Sign-in into your website, insert the following script into the head section of your HTML code:


<!-- OTPLESS SDK -->
<script
  id="otpless-sdk"
  type="text/javascript"
  data-appid="YOUR_APP_ID"
  src="https://otpless.com/v2/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.

Note:- Replace YOUR_APP_ID with your actual App ID provided in your OTPLESS dashboard.

Step 2: Create the OTPLESS Login UI

Insert the following div in your login or sign-up page where you want the OTPLESS login UI to appear:


<!-- OTPLESS Login UI -->
<div id="otpless-login-page"></div>

Ensure your site is served over HTTPS to enable the sign-in widget to load properly. For local development, consider using tools like ngrok to create a secure tunnel.

Step 3: Handle Authentication Callback

Implement a callback function to process authentication responses. Add this script to your page:


  useEffect(() => {
   window.otpless = (otplessUser) => {
     alert(JSON.stringify(otplessUser));
   };
  }, []);

🏁 Checkpoint

To ensure a smooth integration process:

  1. Deploy your app/website with the included OTPLESS SDK.
  2. Conduct tests to verify the sign-in flow functions correctly.
  3. Ensure that after a successful sign-in, the user is redirected back to your app/website and their information is correctly logged in the console.

After the user successfully authenticates, their information will be logged in the console as follows:

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!
