Register a synced passkey (FIDO2)

This article shows how users can register a synced passkey (FIDO2) by using the Passkey flow. A synced passkey is stored in a passkey provider (such as iCloud Keychain or Google Password Manager) and syncs across the user's devices. For an overview of synced passkeys, see Synced passkeys in Microsoft Entra ID.

    The steps to enable passkey providers on Android might vary based on the make and model of your device. Search for Passkey on your device settings, or consult your device manufacturer for guidance. If your device runs Android 14 and you can't enable Authenticator as a passkey provider, we recommend that you upgrade to Android 15.
