In today’s digital age, security is more important than ever. Traditional login methods, like passwords, are often the weakest link in web security. To address this, many developers are turning to advanced authentication methods like facial recognition.
In this tutorial, we will introduce you to FACEIO, a cutting-edge facial authentication framework that can be seamlessly integrated into your website with just a few lines of JavaScript. By the end of this guide, you’ll have a fully functional facial recognition login system on your site, providing your users with a secure and modern authentication experience.
FACEIO is a facial authentication framework designed to simplify the process of adding facial recognition capabilities to websites and web applications. It allows users to log in or sign up using just their face, eliminating the need for traditional passwords or even OTPs. FACEIO enhances security while providing a frictionless user experience.
Before we dive in, here’s what you’ll need:
The first step is to create your FACEIO account and get your hands on an API key. Don’t worry—this part is easy!
Now, let’s get to the fun part: integrating FACEIO into your website. We’ll start with a basic HTML file.
Here’s a simple example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>FACEIO Integration Example</title>
</head>
<body>
<h1>Login with FACEIO</h1>
<button id="faceio-button">Authenticate with Face</button>
<!-- Include the FACEIO JavaScript SDK -->
<script src="https://cdn.faceio.net/sdk.js"></script>
<script>
// Initialize FACEIO with your API key
const faceio = new faceIO("your-api-key-here");
// Handle the button click event to initiate facial authentication
document.getElementById("faceio-button").addEventListener("click", async () => {
try {
// Perform authentication using FACEIO
const response = await faceio.authenticate();
// If successful, greet the user
alert(`Hello, ${response.payload.userName}!`);
} catch (err) {
// Handle authentication errors
console.error(err);
alert("Authentication failed, please try again.");
}
});
</script>
</body>
</html>
Let’s take a closer look at what’s happening in the code:
1.Including the SDK:
The FACEIO JavaScript SDK is what makes all the magic happen. We include it by adding this script tag to our HTML:
<script src="https://cdn.faceio.net/sdk.js"></script>
2.Initializing FACEIO:
We kick things off by initializing FACEIO with the API key you got earlier:
const faceio = new faceIO("your-api-key-here");
Just replace "your-api-key-here" with your actual API key, and you’re good to go!
3.Handling Authentication:
When the user clicks the "Authenticate with Face" button, the following code runs:
document.getElementById("faceio-button").addEventListener("click", async () => {
try {
// Perform authentication using FACEIO
const response = await faceio.authenticate();
// If successful, greet the user
alert(`Hello, ${response.payload.userName}!`);
} catch (err) {
// Handle authentication errors
console.error(err);
alert("Authentication failed, please try again.");
}
});
