Passkeys can be synchronized across devices in the same ecosystem. For example, passkeys created on iOS or in Safari on macOS are stored in iCloud Keychain. Passkeys created in Chrome on Android are stored in the Google Password Manager.
Passkeys are an emerging technology and supported environments are still evolving. As of January 2023, Chrome on macOS and Windows stores passkeys on the local device only.
Google Password Manager
Google Password Manager stores, serves and syncs passkeys on Android. Passkeys from Google Password Manager are available to all Android apps, including Chrome and other browsers. Passkeys are stored when the user creates a passkey on an Android device, and synced; their passkeys are synced with user's other Android devices, and their passkey secrets are encrypted end-to-end. This makes passkeys available to the user across all Android devices that use Google Password Manager, as long as they are signed in with the same Google account.
Passkey support for Android apps
Android apps on Android OS 9 or later support passkeys through the Credential Manager alpha.
