Local Authenticator

(create and use passkeys from the local device)

Supported

External Authenticator

(create and use passkeys from another device)

Planned

Overview

The platform authenticator in Android 9+ has the following capabilities:

creating and using passkeys that are backed up to Google Password Manager
using a passkey from the local Android device to sign into services on another device (such as a laptop or desktop), using FIDO Cross-Device Authentication

Android devices can be persistently linked to the browsers/platforms below:

macOS (Safari and native apps), iOS (global), and iPadOS (global) do not support persistent linking.

When an authenticator is not persistently linked, a QR code must be scanned on every use.

Credential Manager is a new Android Jetpack API that supports multiple sign-in methods, including passkeys, in a single API, thus simplifying the integration for developers.
The Device Public Key (DPK) extension is supported in beta, but is currently gated behind a flag in Chrome. Developers can enable chrome://flags/#enable-experimental-web-platform-features to experiment with DPK on Android, or on desktop Chrome when using Cross-Device Authentication with an Android device.
