Using Your YubiKey 4 or NEO with the Windows Hello App

Update - September 24th 2019: 
The YubiKey for Windows Hello app has been retired and removed from the Windows store; this article has been left up for information purposes only. We'd like to thank our customers for their feedback on this app. We recommend Windows users use our new tool, Yubico Login for Windows, which secures local accounts by adding a layer of protection beyond passwords with the YubiKey.
We hope to bring further updates in future as Microsoft continues to commit to integrating FIDO2 support into their ecosystem. Please contact Yubico Customer Support with any feedback you have on potential future releases or feature requests.

Why? The framework that the YubiKey for Windows Hello app was built on, the Companion Device Framework, will be deprecated by Microsoft. Instead, Yubico is focusing development on improving our existing offering for Local Windows Login (the Windows Logon Tool), while Microsoft continues to prove they are committed to integrating FIDO2 support into their ecosystem. It's also important to point out that the Companion Device Framework is only used for unlocking user accounts (the user must first log into their account, lock the system, and then the YubiKey can be used for unlock).

To set up your YubiKey to unlock your Windows 10 system follow  these instructions. 


  • Microsoft Windows 10 Home, Pro, or Enterprise edition.

    • Anniversary Edition (Version 1607 required with build 14393.321 or later).

    • TIP: To verify the version of Windows you are running, press the Windows key, then type r, select Run, and type winver. The About Windows dialog box. displays information on the version and build number of Windows 10.

  • An applicable YubiKey (YubiKey 5 series not supported)

  • CCID mode enabled on the YubiKey. See Enabling or Disabling Connection Interfaces.

  • Cloud user account.

  • Your local security policy set to allow companion devices for secondary authentication (see below).

  • A PIN set (under sign-in options) for the user on the system who will be using the YubiKey (required).

Downloading and Installing the YubiKey for Windows Hello app

  1. From the Windows app store, locate the YubiKey for Windows Hello app.
  2. Click Get.
  3. When installation is completed, click Launch.

To access the YubiKey for Windows Hello app

  • From the Start menu, select All Apps >Start > YubiKey for Windows Hello

To uninstall the YubiKey for Windows Hello App

Be sure you have unregistered any YubiKeys before you uninstall the app.

  1. In the Start menu, navigate to the YubiKey for Windows Hello app.
  2. Right-click the app and select Uninstall.
  3. Follow the prompts. It is not necessary to reboot your computer.

Setting Local Security Policy to Allow Companion Devices

On systems running Windows Pro or for Windows Enterprise systems, you must set the option to “Allow Companion Device For Secondary Authentication” in the Local Security Policy. If your organization manages your security policy, contact your IT administrator and request this change before installing this app. You cannot change local security policy on systems running Windows Home, however this option is enabled by default.

To modify local security policy

  1. Open the Local Group Policy Editor. To do this, press the Windows key, type R, and then type gpedit.msc.
  2. In the Local Group Policy Editor, from the top level Local Computer Policy, navigate to Computer Configuration > Administrative Templates > Windows Components > Microsoft Secondary Authentication Factor.
  3. In the right pane, click the link to Edit policy setting. (You can also double-click the setting to “Allow Companion Device For Secondary Authentication.”) The default state is Not Configured.
  • If the policy is displaying Not Configured or Enabled, then you do not have to make any additional changes. Click Cancel.
  • If the setting is displayed as Disabled, continue with the next step.
  1. In the setting screen, select the option for Enabled, and click OK.
  2. Exit the Local Group Policy Editor and the Management Console.


  • This app is used to unlock your system only — it will not work with login (waking from sleep/hibernating requires a login).
  • This app allows you to register a maximum of four YubiKeys per account.
  • You cannot register the same YubiKey to more than one account on the same system.
  • You may notice that the YubiKey NEO is slower than the YubiKey 4. When you use a YubiKey NEO to unlock your system, we recommend you swipe the screen or press any key (rather than tapping the YubiKey).
  • We recommend using this app only on single-user Windows systems; this app does not support multiple users.

Known Issues

  • Yubico Authenticator with password set. Your YubiKey will not work for unlocking your system if you use Yubico Authenticator and have a password set.
  • Requiring the YubiKey. There is currently no way to require the YubiKey to unlock your system — you can always access your account using your PIN or password. These are limitations of the Companion Device Framework.
  • Removing all keys. If you have removed all YubiKeys but have not uninstalled the app, you are still prompted to use the YubiKey to unlock your system. To work around this issue, uninstall the app.
  • Removing a key. If you try to remove a YubiKey and the key is not inserted into your system, two OATH credentials will be present. You would need to delete these using an older version of Yubico Authenticator (2.3.0 or older) or by resetting the entire OATH applet (using Yubico Authenticator).
  • Resetting the OATH applet on the YubiKey. If you use the opensc-tool or Yubico Authenticator to reset the OATH applet on the YubiKey, you will erase the credentials that you have registered for the YubiKey for Windows Hello app.

Frequently Asked Questions

  • When I try to register a YubiKey with the YubiKey for Windows Hello app, why do I receive an error?

It may be because your local security policy needs to be set to allow companion devices (this applies only to systems running Windows Pro or Windows Enterprise). To change your local security policy to allow companion devices, see the steps in the previous section.
