Step 1: Load the OTPLESS JS

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


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: Configure Authentication and UI

Step 4: Handle Authentication Callback

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

mounted() {
 window.otpless = (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.

The structure of the user information returned upon successful sign-in is as follows:

  "status": "SUCCESS",
