Answer
Can a PWA use Face ID or Touch ID?
Yes. The Web Authentication API (WebAuthn) lets a PWA prompt for the device’s built-in biometric authenticator — Face ID and Touch ID on Apple devices, Windows Hello on PC, or a fingerprint sensor on Android — to register or verify a user without ever handling the raw biometric data, which stays on-device. It is widely supported across modern Chrome, Safari, Edge and Firefox.
How it works
The site never sees fingerprint or face data — the OS authenticator verifies the user locally and returns a signed cryptographic credential to the page.
Common use case
Passwordless login (passkeys) and step-up authentication for sensitive actions like payments, without needing a native app.
Support
Broadly supported in Chrome, Safari, Edge and Firefox on both desktop and mobile as of 2026.
