FIDO2 WebAuthn global MFA settings

You can allow users to register their FIDO2 authenticators as a login multi-factor authentication (MFA) option. Set how many devices users can register and whether users can remove their own devices. For FIDO2 authenticators, you can require user verification for device registration and authentication.

Note

FIDO2 authenticators could be known as external security keys or built into devices like phones and laptops. In the Identity Platform UI, the term device is interchangeble to mean either device or security key.

When you configure and save the global settings for FIDO2, it automatically generates a FIDO2 registration and management page.

Note

The FIDO2 registration and authentication web page for your end users requires HTTPS in the URL.

The FIDO2 registration and management page is localized and translated based on the user's browser language settings.

To guide end users to register their devices as FIDO authenticators, share the FIDO2 registration page URL. Once end users register their device on that page, it becomes available as a FIDO2 login option to authenticate their access to resources.

  1. On the left side of the Identity Platform page, click Multi-Factor Methods.

  2. Click the pencil icon for FIDO2 (WebAuthn).

    The configuration page for FIDO2 (WebAuthn) appears.

  3. In the Register and Manage Devices section, set the following configurations.

  4. In the User Device Settings section, set the following configurations.

    Set how many FIDO2-enabled devices a user can register. Valid values are Unlimited, 1, 5, and 10.

    Allow device replacement

    Set whether to allow replacement of a device when the user has reached the maximum number of registered devices.

    The next admin setting determines which device to replace. This information is not displayed to the end user; they are only prompted to replace a device.

    Replacement Order

    This option is active only when the Allow device replacement option is selected. Choose which device to automatically replace:

    • Oldest by creation date/ time - the last time the user registered the device

    • Oldest by date time last accessed - the last time the device was used in the system

    Allow device removal

    Set whether to allow users to remove their own device from the FIDO2 registration and management page.

  5. In the Device Restriction section, set whether users must provide verification (for example, PIN) for enrollment and verification while using a FIDO2 authenticator, like a security key or mobile device.

    Note

    Some browsers and operating systems might not have PIN support for FIDO2 authenticators. To learn more, see Admin troubleshooting PIN support for FIDO2 WebAuthn.

  6. Click Save.

    This creates the FIDO2 registration page and provides the registration URL. Share this URL with your end users to register and manage their FIDO2 devices.

    Note

    If you turn off FIDO2 as a login method, it prevents end users from seeing it as an MFA choice during login. The FIDO2 Enrollment URL page stays active for end users to manage their FIDO2 devices.

Next steps

  • Configure a policy on the Multi-Factor Methods tab to use FIDO2 as an authenticator in the login workflow.

  • Copy and share the FIDO2 Enrollment URL with your end users. For example, to encourage end users to register their FIDO2 devices, customize the "Passwordless with FIDO2" setup instructions available in the SecureAuth Onboarding Toolkit.

    The FIDO2 registration and authentication web page for your end users requires HTTPS in the URL.
