How eOTP Works

eOTP is a robust one-time password (OTP) solution designed to secure your applications with minimal effort. It integrates seamlessly into your existing systems, delivering OTPs via multiple channels to ensure user authentication is both fast and reliable.

Whether you’re protecting user logins, sensitive data, or adding an extra layer of security, eOTP scales with your needs.

Generating an appCode Token

To use eOTP, you’ll need an `appCode` token, which authenticates your application with our servers. Follow these steps to generate one:

1. Log in to your eOTP dashboard at dashboard.eotp.io.
2. Navigate to the API Keys section.
3. Click Generate New Token and name it (e.g., "MyApp-Prod").
4. Copy the generated `appCode`—it will only be shown once for security.
5. Store it securely in your application’s environment variables.

Using eOTP in Your Application

Once you have your `appCode`, integrating eOTP is simple. Include the eOTP JavaScript library and initialize it with your token. Below are examples for different use cases.

Basic Initialization

Start by adding the library and initializing it with your `appCode`.

<script src="https://eotp.io/eotp.js"></script>
<script>
    eOTP.init({
        appCode: "your-appCode-here",
        method: "sms"
    });
</script>

Sending an OTP

Trigger an OTP to a user’s phone or email.

eOTP.send({
    destination: "user@example.com", // or "+1234567890"
    method: "email" // sms, whatsapp, voice, email
}).then(response => {
    console.log("OTP sent:", response);
}).catch(error => {
    console.error("Error:", error);
});

Verifying an OTP

Verify the OTP entered by the user.

eOTP.verify({
    destination: "user@example.com",
    code: "123456" // User-entered OTP
}).then(response => {
    if (response.valid) {
        console.log("OTP verified!");
    } else {
        console.log("Invalid OTP");
    }
}).catch(error => {
    console.error("Error:", error);
});

Custom Options

Customize delivery methods and behavior.

eOTP.init({
    appCode: "your-appCode-here",
    method: "whatsapp",
    timeout: 300, // OTP expires in 5 minutes
    length: 6, // 6-digit OTP
    template: "Your eOTP code is {{code}} - Secure your galaxy!"
});
