Question details

Users are unable to complete the setup of FIDO2 security keys due to a correlation error, even though FIDO2 is activated for the organization.

How to Troubleshoot FIDO2 Passkey and Security Key Setup Errors

Product: Microsoft Entra
Device & OS: Windows 11
Scenario: Registering a new FIDO2 security key or passkey for multi-factor authentication (MFA).
Observed behavior: The registration process fails with a correlation error, and the issue persists across different web browsers and devices.

Before you start

Ensure you have Microsoft Entra administrator privileges to review authentication policies and verify that the security keys you are attempting to register are FIDO2 compatible.

Solution 1Recommended

Verify FIDO2 Compatibility and Update Authentication Policies

Use this method to ensure your organization's Microsoft Entra policies properly allow FIDO2 passkeys and that the user's hardware meets the requirements.

Even when FIDO2 is enabled globally, specific authentication method policies or outdated operating systems can trigger correlation errors during the registration process.

Check Security Key Compatibility

Verify with the manufacturer that your physical security key is a fully compatible FIDO2 device supported by Microsoft.

Update Operating System and Browsers

Ensure that the Windows 11 operating system and the web browsers (Edge, Chrome, etc.) used for registration are updated to their latest versions.

Review Authentication Methods Policy

Log into the Microsoft Entra admin center, navigate to Protection > Authentication methods > Policies, and confirm that the policy explicitly permits the use of FIDO2 passkeys for the affected users.

Register via Security Info Page

Instruct the user to navigate to their 'My Sign-Ins' Security info page, select 'Add method', choose 'Security key', and carefully follow the on-screen prompts.

Verify FIDO2 Compatibility and Update Authentication Policies

Policy Application: Policy changes in Microsoft Entra may take a few minutes to propagate. Wait briefly before asking the user to try the registration again.

Solution 2

Reset Security Information and Escalate to Support

If policy and compatibility checks fail, resetting the user's existing security info can clear corrupted authentication states.

Frequently Asked Questions

What does a correlation error mean in Microsoft Entra?

A correlation error indicates a backend failure or mismatch during the authentication or registration process. It often occurs due to misconfigured policies, unsupported hardware, or temporary communication issues between the device and Azure servers.

Which security keys are compatible with Microsoft Entra FIDO2?

Microsoft Entra supports security keys from vendors that are FIDO2 CTAP1 and CTAP2 compliant, including popular options from YubiKey, Feitian, and other Microsoft-verified FIDO2 partners.

How do I find the correlation ID for a Microsoft support ticket?

When the error screen appears during the FIDO2 setup, the correlation ID is typically displayed at the bottom of the error message box alongside the timestamp. You can copy this alphanumeric string directly from the screen.

Why does the FIDO2 setup fail even when enabled for the organization?

Even if globally enabled, the setup can fail if the specific user or group is excluded in the Authentication methods policy, if the security key itself is not supported, or if the operating system and browser lack the necessary WebAuthn updates.
