Passkeys can be synchronized across devices in the same ecosystem. For example,passkeys created on Android are stored in the Google Password Manager.

Passkeys are an emerging technology and supported environments are stillevolving. As of August 2023, Chrome on macOS and Windows stores passkeys on thelocal device only.

Google Password Manager

Google Password Manager stores, serves and synchronizes passkeys on Android andChrome. Passkeys from Google Password Manager are available to all Android apps,including Chrome and other browsers. When the user creates a passkey on anAndroid device it's stored and synchronized with their other Android devices,and their passkey secrets are encrypted end-to-end. This makes passkeysavailable to the user across all Android devices that use Google PasswordManager and are signed in with the same Google Account.

Google Password Manager on Chrome helps create and sign in with passkeys.Depending on the desktop operating system (e.g. ChromeOS, iOS, macOS, Windows)users may be presented with a QR code to securely use a passkey stored on theirmobile device, or a notification may be displayed prompting the user to unlocktheir phone to use the relevant passkey.
