# Registering Passkey for Passwordless authentication

Passkeys provide a faster, more secure way to sign in without entering a password. Once enabled by your organization and registered on your account, a passkey can be used to authenticate using a trusted device, biometric verification (such as fingerprint or face recognition), a PIN, a security key, or a supported password manager.

This article explains the registration process, supported registration methods, sign-in experience, and known limitations of passkey authentication in OneIdP.

### Before You Begin

1. Passkey settings should be enabled for your Directory (from [**Directory Settings**](/docs/directory-settings#passwordless-methods))

### How Passkey Registration Works

1. Enter your OneIdP credentials on the respective SSO Application or User Portal, and sign in.

2. To register, complete any required authentication steps, such as:

  - Password verification
  - Managed device verification
  - One-time password (OTP) verification
  - Other configured sign-in requirements (Compliance etc.)
3. After the required verification steps are completed, you will see a prompt to register a passkey. You can choose one of the following:

  - [**Set Up a Passkey**](/v1/docs/registering-passkey-for-passwordless-authentication#setting-up-a-passkey)**:** This will prompt you to register a passkey (explained below).
  - **Skip for Now:** This will allow you to continue signing in without registering a passkey using your existing authentication requirements. You can register a passkey during a future sign-in when prompted.

### Setting Up a Passkey

1. When you select **Set Up a Passkey**, your browser or device (based on platform) will display a passkey registration prompt.
2. Depending on your device and organization settings, you can register a passkey using:

  1. **Windows:** A built-in authenticator such as fingerprint, face recognition, or device PIN
  2. **iPhone, iPad or Android:** This option requires scanning a QR code with your phone or tablet. When prompted, tap **Use passkey** or use the QR scanner on your device. If you choose to save the passkey on your phone or tablet, Bluetooth pairing may be required to verify the device.
  3. **Security key:** You will get a prompt to insert the key in the device and set up key
  4. **Password Manager**: You can store your passkey in Google Password Manager or any other credential manager that supports syncing.
3. Follow the on-screen instructions to complete registration.

6. Enter the OTP you have received in the authenticator app and click LogIn ![](https://cdn.document360.io/175c0eac-012f-4410-bdc5-ac60794f82d8/Images/Documentation/image-A0V3M09E.png)

### Known Behaviors

1. Passkey authentication is not currently supported in most native applications.
2. Users cannot register a passkey on Windows devices when both Keycard and Just-In-Time (JIT) provisioning are enabled.
3. Passkey registration using NFC on Android devices is currently not supported. However, NFC-based passkey authentication works as expected for previously registered passkeys.
4. Users can continue to sign in using a registered passkey even when a different Identity Provider (IdP) is configured for authentication.
