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

Platform Notes

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.
