Introducing FACEIO - Facial Authentication for the Web

Hi Community!

We are pleased to introduce FACEIO, a product developed from scratch here at PixLab in the past few years. We look forward to hear your thoughts about this...


FACEIO is a facial authentication framework that can be implemented on any website via simple JavaScript snippet (just like Disqus or Google Tag) to easily authenticate users via Face Recognition instead of the traditional login/password pair or OTP code. Get started here.

Now, the Details,

FACEIO is a cross-browser, Cloud & On-Premise deployable, facial authentication framework, with a client-side JavaScript library (fio.js) that integrates seamlessly with any website or web application desiring to offer secure facial recognition experience to their users.

Put it simply, FACEIO is the easiest way to add passwordless authentication to web based applications. Simply implement fio.js on your website, and you will be able to instantly authenticate your existing users, and enroll new ones via Face Recognition using their computer Webcam or smartphone frontal camera on their favorite browser.

Some Nice Features

  • Authenticates and confirms identity of users instantly without FIDO keys, OTP codes, or security questions.
  • Full cross-browser compatibility (Chrome, Firefox, Safari, Edge & Chromium derivatives).
  • Zero external dependency. Only standard technology implemented in plain JavaScript & CSS.
  • Defense grade accuracy with less than 100 milliseconds recognition speed powered by state-of-the-art facial recognition engines.
  • Highest security standards. Privacy by design with maximum user convenience. No requirements for biometric sensor.

FACEIO works with regular Webcams or smartphones frontal camera on all modern browsers, does not require biometric sensors to be available on the client side, and works seemingly with all websites and web-based applications regardless of the underlying front-end JavaScript framework or server-side language or technology.

Adding FACEIO to your website or web-based application

Implementing FACEIO on your website or webapp is straightforward. Before so, you need to create a new application first on the FACEIO Console, and link this resource to your website or web application. The checklist below highlights the steps to follow for a smooth integration of
fio.js on your site:

  1. Create a new FACEIO application first: Follow the Application Wizard on the FACEIO Console to create your first application and link it to your website or web application.
  2. The Application Wizard should automate the creation process for you. Usually, this involve inputting an application name, selecting a facial recognition engine, cloud storage region, reviewing security options, customizing the Widget layout, and so forth... FACEIO Application Wizard
  3. Once your first FACEIO application created, simply implement fio.js, our facial recognition JavaScript library on your website, and initialize the library with your application Public ID.
  4. Congratulations 👏. You have FACEIO up & running! Now, it's time to enroll() and authenticate() your first user via face recognition as we will see on the HTML boilerplate..

Enroll New User

The HTML Integration Boilerplate

Understand the fundamentals

  • To enroll (register) a new user, simply call the enroll() method from the recently instantiated faceIO object. The enroll() method let you transactionally enroll new users on your application. A process better known as on-boarding. It is the equivalent implementation of a standard register/sign-up function in a traditional password managed, authentication system. This is done on line 31 of the gist above.
  • Effective call to enroll(), will trigger the FACEIO Widget, ask for user’s consent (if not yet authorized), request access (if not yet granted) to the browser’s Webcam/Frontal camera stream, and finally extract & index the facial features of the enrolled user for future authentication purposes.
  • enroll() takes a number of Optional Parameters including locale for the interaction language, permissionTimeout which correspond to the number of seconds to wait for the user to grant camera access permission, but more importantly, enroll() accept a payload which simply put, an arbitrary set of data you can link to this particular user such as an Email Address, Name, ID, etc. This payload will be forwarded back to you upon successful future authentication of this particular user.

👉 The enroll() method, its expected parameters, Promise fulfillment, error handling, etc. are officially documented here.

  • To Authenticate & Recognize a previously enrolled user, simply call the authenticate() method from the recently instantiated faceIO object. The authenticate() method let you transactionally authenticate (recognize) previously enrolled users on your application. It is the equivalent implementation of a standard login/sign-in function in a traditional password managed, authentication system.
  • authenticate() returns a Promise whose fulfillment handler receives a userData object when the user has successfully been identified. The most important fields of this object are: payload, which is the arbitrary data you have already linked (if any) to this particular user during his enrollment via the payload parameter, the enroll() method takes, and Facial ID, which is an Universally Unique Identifier assigned to this particular user during his enrollment. This Facial ID alongside the payload data could serve as a lookup key on your backend to fetch data linked to this particular user on each future successful authentication for example.
