How FACEIO Works
Facial Authentication
Facial Authentication
Directly in the Browser
FACEIO adds a guided enrollment and authentication widget to websites and mobile web apps. Your backend keeps control of user accounts, access rules, recovery, and authorization.
With FACEIO, You Can:
-
Register new users and authenticate returning users from the browser
-
Present your notice and obtain consent before facial enrollment begins
-
Use liveness checks and the default PIN Code validation in your login flow
-
Send the result to your backend, where your application grants or denies access
Choose the Facial Recognition Engine
Select and configure the facial recognition engine used by your FACEIO application from the Console.
Control Consent and Deletion
Your website or web app presents the required notice, obtains consent, and provides a deletion process. FACEIO does not store or access biometric hashes.
Use Cloud or On-Premises Deployment
Use a supported cloud engine or deploy PixLab Insight in your own infrastructure when you need local processing and infrastructure control.
Add One JavaScript Library
Load fio.js, initialize it with your App Public ID, and call the method your user flow needs. No browser extension, native app, or dedicated biometric sensor is required.

FACEIO ID Match
Match a Live Selfie to an ID Portrait
FACEIO ID Match is a browser widget that guides the user through capturing an ID document and a live selfie. It runs a liveness check, compares the selfie with the portrait extracted from the ID, and can return selected document fields.
ID scanning and optional field extraction are powered by the PixLab DOCSCAN API, which supports 11K+ ID document formats across over 197 countries and territories. ID Match does not authenticate the document or replace KYC.
Captured images and scan data are processed in RAM and deleted after the result is generated, whether the match succeeds or fails. No ID scan data or processing logs are retained. Your application remains responsible for document validation and every downstream decision.
What ID Match Does
- Guides the user through ID document capture, live selfie capture, a liveness check, and a 1:1 face comparison.
- Powered by PixLab DOCSCAN for broad document coverage, including passports, national IDs, driver's licenses, visas, and residence permits.
- Returns the selfie-to-portrait match result, liveness result, and any document fields you requested.
- Runs in desktop and mobile browser sessions without requiring a native mobile app.
- Can be used during account creation, then paired with FACEIO facial authentication for future passwordless login.
Keep Selfie-to-ID Matching Inside Your Web Flow
ID Match compares two faces and optionally extracts document fields. It does not authenticate the ID document, perform KYC or AML checks, or decide whether a user should be approved.

Common Questions About FACEIO
Understand what FACEIO does, how it integrates with your website, and which responsibilities remain with your application.
What does FACEIO do?
FACEIO adds facial authentication to websites and web apps. New users enroll through fio.js, returning users authenticate with their face, and your backend uses the returned result to create a session or apply its own access rules.
How do I add FACEIO to my website?
Create a FACEIO application in the Console, copy its App Public ID, load and initialize fio.js, then call enroll() for new users and authenticate() for returning users.
Does FACEIO store biometric hashes?
No. FACEIO, including the fio.js library, embedded widget, REST API, and Console, does not store, handle, or access biometric hashes. The facial recognition engine selected by the application owner manages biometric hashes according to the application's configuration and consent flow.
Which security controls does FACEIO provide?
FACEIO provides liveness and anti-spoofing checks, PIN Code validation enabled by default, and domain restriction options. Application owners remain responsible for backend authorization, account recovery, rate limits, and other controls required by their service. Review the security best-practice guide before production use.
Does FACEIO support accessible authentication?
The FACEIO widget includes visual and audio instructions, keyboard navigation, and screen-reader support with compatible browsers and assistive technologies. Application owners should test the complete flow and provide an alternative access method for users who cannot or do not want to use facial authentication.
