What is eOTP?

eOTP is a lightweight, embeddable one-time password solution that lets you add strong authentication to any website, form, or document with just a few lines of code. No backend infrastructure required.

Deliver OTPs via SMS, WhatsApp, Email, or Voice Call, and receive a secure verification token upon success.

Generating an AppCode

The appCode is your unique identifier that connects your application to the eOTP service.

1. Log in to your eOTP Dashboard
2. Navigate to the AppCodes section
3. Click Create New AppCode
4. Give it a name and whitelist your domain (e.g. https://yourdomain.com)
5. Select your default and backup delivery methods
6. Copy the generated AppCode and store it securely

Integrating eOTP

Follow these steps to add OTP verification to your site.

Step 1: Include the Script

<script src="https://api.e-otp.com/eotp.js"></script>

Step 2: Add a Container

<div id="eotp-container"></div>

Step 3: Initialize & Start Verification

<script>
EmbedOTP.init({
    appCode: "your-app-code-here",
    container: "#eotp-container",
    msisdn: "+27821234567",
    email: "user@example.com",
    onSuccess: function(token) {
        console.log("Verification successful. Token:", token);
        // Send token to your backend for validation
    }
}).then(() => {
    EmbedOTP.startVerification("#eotp-container");
});
</script>
