This article shows how to register a Microsoft Entra passkey on Windows. A Microsoft Entra passkey on Windows is a device-bound passkey stored in the local Windows Hello container. Unlike synced passkeys, a passkey on Windows doesn't sync across devices — each device requires a separate passkey registration. This approach enables phishing-resistant sign-in with a Windows Hello biometric or PIN, without requiring the device to be Microsoft Entra joined or registered.
For an overview of Microsoft Entra passkey on Windows and how it compares with Windows Hello for Business, see Microsoft Entra passkey on Windows.
Prerequisites
Confirm these requirements before you register:
- Your administrator enabled passkeys (FIDO2) and created a passkey profile that allows Windows Hello AAGUIDs. For configuration steps, see Configure a profile for Microsoft Entra passkey on Windows.
- The device runs a supported version of Windows.
- Attestation must not be enforced in the passkey profile.
For the list of supported Windows Hello passkey AAGUIDs, see Supported Windows Hello passkey AAGUIDs.
