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:

index.html
<-- OTPLESS SDK -->
<script
  id="otpless-sdk"
  type="text/javascript"
  src="https://otpless.com/v3/auth.js"
  data-appid="YOUR_APP_ID"
></script>

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:

login.html
<-- 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:

index.html
mounted() {
 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.

User Information Response Structure

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

{
  "status": "SUCCESS",
  "token": "unique_token_here",
  "userId": "unique_user_id_here",
  "timestamp": "ISO_timestamp_here",
  "identities": [
    {
       "identityType": "EMAIL",
      "identityValue": "user@example.com",
      "channel": "OAUTH",
      "methods": [
        "GOOGLE"
      ],
      "name": "User Name",
      "verified": true,
      "verifiedAt": "ISO_timestamp_here",
      "isCompanyEmail": "true"
    }
  ],
  "idToken": "jwt_token",
  "network": {
    "ip": "127.0.0.1",
    "timezone": "Asia/Kolkata",
    "ipLocation": {}
  },
  "deviceInfo": {},
  "sessionInfo": {},
  "firebaseInfo": {},
}
