Have you ever wondered how to enable biometric authentication on the web? This codelab walks you through how to use WebAuthn to implement reauthentication experience on your website using a biometric sensor. 


Before you begin

The Web Authentication API, also known as WebAuthn, lets you create and use origin-scoped, public-key credentials to authenticate users.


The API supports the use of BLE, NFC, and USB-roaming U2F or FIDO2 authenticators - also known as security keys - as well as a platform authenticator, which lets users authenticate with their fingerprints or screen locks.


In this codelab, you build a website with a simple reauthentication functionality that uses a fingerprint sensor. Reauthentication protects account data because it requires users who already signed in to a website to authenticate again when they try to enter important sections of the website or revisit the website after a certain amount of time.


Prerequisites

- Basic understanding of how WebAuthn works

- Basic programming skills with JavaScript


What you'll do

- Build a website with a simple reauthentication functionality that uses a fingerprint sensor


What you'll need

- An Android device, preferably with a biometric sensor

- An iPhone or iPad with Touch ID or Face ID on iOS 14 or higher

- A MacBook Pro or Air with Touch ID on macOS Big Sur or higher

- Windows 10 19H1 or higher with Windows Hello set up


One of the following browsers:
