Stay organized with collections Save and categorize content based on your preferences.

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 October 2022, 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 synch'd 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

A new API set that will offer full passkeys support for Android apps will be released soon. Subscribe to the newsletter to get notified about updates.

Android

Passkeys generated in Chrome on Android are stored in the Google Password Manager. These passkeys are available on all other Android devices as long as Google Password Manager is available and the same user's Google account is signed in.

Windows

Chrome on Windows stores passkeys in Windows Hello, which does not sync them to other devices as of October 2022.

When a user tries to sign in to a website for the first time on Chrome on Windows, they should scan a QR code with another device that already has a passkey. After that, they can create a passkey on the local Windows device for future use there.

macOS

Chrome on macOS stores passkeys in a local profile and does not sync them to other devices as of October 2022. Passkeys from iCloud Keychain are not available in Chrome on macOS.

When a user tries to sign in to a website for the first time on Chrome on macOS, they should scan a QR code with another device that already has a passkey. After that, they can register a passkey on the local macOS device for future use there.

iOS / iPadOS

Chrome on iOS 16 and iPadOS 16 uses iCloud Keychain to store passkeys. Passkeys in iCloud Keychain are synced across the user's Apple devices and can be used by other browsers and apps.

As of October 2022, Chrome on iOS 16 and iPadOS does not yet support passkey autofill.

Linux

Chrome on Linux does not support passkeys with a built-in platform authenticator. Linux users can use passkeys from another device such as an Android phone or an iPhone by scanning a QR code.
