Seamless Face Authentication in Your Next.js App with FACEIO

In this blog post, we'll guide you through the step-by-step process of incorporating FACEIO's face authentication into your Next.js application, from setting up your FACEIO account to implementing the integration within your codebase.

Prerequisites

Before we dive in, make sure you have the following in place:

Node.js and npm: Ensure you have Node.js and npm installed on your development machine. You can download the latest version from the official Node.js website.
Next.js: You'll need to have a Next.js project set up. If you don't have one, you can create a new one:
FACEIO Account: Sign up for a FACEIO account on the FACEIO Console. This is where you'll create your FACEIO application and obtain the necessary credentials.

Setting Up the FACEIO Application

Create a New FACEIO Application: Log in to your FACEIO Console and click on the "Create New App" button.
Configure the Application: Fill out the required information, such as the application name, description, and the callback URL (which will be the URL of your Next.js application). Once you've completed the form, click "Create App".
Obtain the FACEIO_APP_ID: After creating the application, you'll be provided with a unique FACEIO_APP_ID. This is the identifier you'll use to integrate FACEIO into your Next.js application.

Integrating FACEIO into Your Next.js Application

Install the FACEIO NPM Package: In your Next.js project, install the faceio-npm package using npm or yarn:
Create a Face Authentication Component: In your Next.js project, create a new file called Components/Dashboard.tsx (or any other name you prefer) with the following code:

Import your Dashboard.tsx Component into Login.tsx Component:

Remember to replace 'NEXT_PUBLIC_FACEIO_PUBLIC_ID' with the actual FACEIO_APP_ID you obtained from the FACEIO Console.
Integrate the Face Authentication Component into Your Next.js Page: In your Next.js application's main page (e.g., app/page.tsx), import the Home component and render it:

That's it! You've now integrated FACEIO's face authentication into your Next.js application. When users click the "Authenticate with Face" button, the FACEIO widget will appear, guiding them through the authentication process.

To demonstrate the FACEIO widget's functionality, let's capture a GIF of the registration process:

Key Security Best Practices for FACEIO Applications

Eliminate Duplicate Registrations: Enable settings to stop the same user from enrolling multiple times, avoiding potential conflicts or misuse.
Enhance Anti-Spoofing Measures: Activate features to detect and block face spoofing attempts, ensuring the system only interacts with real, live users.
Guarantee PIN Uniqueness: Make sure each user's PIN is unique within the application to prevent unauthorized access.
Implement Geo-Restrictions: Limit the instantiation of the FACEIO widget to authorized domain names and countries for added security control.

Benefits of Using FACEIO in Your Next.js App

Integrating FACEIO into your Next.js application offers several benefits:

Improved User Experience: The FACEIO widget offers a seamless and intuitive authentication flow, making it easy for users to log in to your application.
Cross-Platform Compatibility: FACEIO works across various devices and browsers, ensuring a consistent user experience.
Easy Integration: The faceio-npm package simplifies the integration process, allowing you to quickly add face authentication to your Next.js application.
