title: Windows Hello and password changes (Windows 10)
description: When you change your password on a device, you may need to sign in with a password on other devices to reset Hello.

# Windows Hello and password changes
**Applies to**
- Windows 10
- Windows 10 Mobile
When you set up Windows Hello, the PIN or biometric gesture that you use is specific to that device. You can set up Hello for the same account on multiple devices. If the PIN or biometric is configured as part of Windows Hello for Business, changing the account password will not impact sign-in or unlock with these gestures since it uses a key or certificate. However, if Windows Hello for Business is not deployed and the password for that account changes, you must provide the new password on each device to continue to use Hello.
## Example
Let's suppose that you have set up a PIN for your Microsoft account on **Device A**. You use your PIN to sign in on **Device A** and then change the password for your Microsoft account.
Because you were using **Device A** when you changed your password, the PIN on **Device A** will continue to work with no other action on your part.
Suppose instead that you sign in on **Device B** and change your password for your Microsoft account. The next time that you try to sign in on **Device A** using your PIN, sign-in will fail because the account credentials that Hello on **Device A** knows will be outdated.
> **Note:**  This example also applies to an Active Directory account when [Windows Hello for Business is not implemented](implement-microsoft-passport-in-your-organization.md).
 
## How to update Hello after you change your password on another device
1. When you try to sign in using your PIN or biometric, you will see the following message: **Your password was changed on a different device. You must sign in to this device once with your new password, and then you can sign in with your PIN.**
2. Click **OK.**
3. Click **Sign-in options**.
4. Click the **Password** button.
5. Sign in with new password.
6. The next time that you sign in, you can select **Sign-in options** and then select **PIN** to resume using your PIN.

# Windows Hello biometrics in the enterprise
**Applies to:**
- Windows 10
Windows Hello is the biometric authentication feature that helps strengthen authentication and helps to guard against potential spoofing through fingerprint matching and facial recognition.
> **Note:** When Windows 10 first shipped, it included Microsoft Passport and Windows Hello, which worked together to provide multi-factor authentication. To simplify deployment and improve supportability, Microsoft has combined these technologies into a single solution under the Windows Hello name. Customers who have already deployed these technologies will not experience any change in functionality. Customers who have yet to evaluate Windows Hello will find it easier to deploy due to simplified policies, documentation, and semantics.
Because we realize your employees are going to want to use this new technology in your enterprise, we’ve been actively working with the device manufacturers to create strict design and performance recommendations that help to ensure that you can more confidently introduce Windows Hello biometrics into your organization.
##How does Windows Hello work?
Windows Hello lets your employees use fingerprint or facial recognition as an alternative method to unlocking a device. With Windows Hello, authentication happens when the employee provides his or her unique biometric identifier while accessing the device-specific Windows Hello credentials.
The Windows Hello authenticator works to authenticate and allow employees onto your enterprise network. Authentication doesn’t roam among devices, isn’t shared with a server, and can’t easily be extracted from a device. If multiple employees share a device, each employee will use his or her own biometric data on the device.
## Why should I let my employees use Windows Hello?
Windows Hello provides many benefits, including:
- It helps to strengthen your protections against credential theft. Because an attacker must have both the device and the biometric info or PIN, it’s much more difficult to gain access without the employee’s knowledge.
- Employees get a simple authentication method (backed up with a PIN) that’s always with them, so there’s nothing to lose. No more forgetting passwords!
- Support for Windows Hello is built into the operating system so you can add additional biometric devices and polices as part of a coordinated rollout or to individual employees or groups using Group Policy or Mobile Device Management (MDM) configurations service provider (CSP) policies.<br>For more info about the available Group Policies and MDM CSPs, see the [Implement Windows Hello for Business in your organization](implement-microsoft-passport-in-your-organization.md) topic.
## Where is Microsoft Hello data stored?
The biometric data used to support Windows Hello is stored on the local device only. It doesn’t roam and is never sent to external devices or servers. This separation helps to stop potential attackers by providing no single collection point that an attacker could potentially compromise to steal biometric data. Additionally, even if an attacker was actually able to get the biometric data, it still can’t be easily converted to a form that could be recognized by the biometric sensor.
## Has Microsoft set any device requirements for Windows Hello?
We’ve been working with the device manufacturers to help ensure a high-level of performance and protection is met by each sensor and device, based on these requirements:
- **False Accept Rate (FAR).** Represents the instance a biometric identification solution verifies an unauthorized person. This is normally represented as a ratio of number of instances in a given population size, for example 1 in 100 000. This can also be represented as a percentage of occurrence, for example, 0.001%. This measurement is heavily considered the most important with regards to the security of the biometric algorithm.
- **False Reject Rate (FRR).** Represents the instances a biometric identification solution fails to verify an authorized person correctly. Usually represented as a percentage, the sum of the True Accept Rate and False Reject Rate is 1. Can be with or without anti-spoofing or liveness detection.
### Fingerprint sensor requirements
To allow fingerprint matching, you must have devices with fingerprint sensors and software. Fingerprint sensors, or sensors that use an employee’s unique fingerprint as an alternative log on option, can be touch sensors (large area or small area) or swipe sensors. Each type of sensor has its own set of detailed requirements that must be implemented by the manufacturer, but all of the sensors must include anti-spoofing measures (required) and a way to configure them (optional).
**Acceptable performance range for small to large size touch sensors**
- False Accept Rate (FAR): &lt;0.001 – 0.002%
- False Reject Rate (FRR) without Anti-spoofing or liveness detection: &lt;5%
- Effective, real world FRR with Anti-spoofing or liveness detection: &lt;10%
**Acceptable performance range for swipe sensors**
- False Accept Rate (FAR): &lt;0.002%
- False Reject Rate (FRR) without Anti-spoofing or liveness detection: &lt;5%
- Effective, real world FRR with Anti-spoofing or liveness detection: &lt;10%
### Facial recognition sensors
To allow facial recognition, you must have devices with integrated special infrared (IR) sensors and software. Facial recognition sensors use special cameras that see in IR light, letting them tell the difference between a photo and a living person while scanning an employee’s facial features. These sensors, like the fingerprint sensors, must also include anti-spoofing measures (required) and a way to configure them (optional).
- False Accept Rate (FAR): &lt;0.001
- False Reject Rate (FRR) without Anti-spoofing or liveness detection: &lt;5%
- Effective, real world FRR with Anti-spoofing or liveness detection: &lt;10%

# Enable phone sign-in to PC or VPN
**Applies to**
- Windows 10
- Windows 10 Mobile
In Windows 10, version 1607, your network users can use Windows Phone with Windows Hello to sign in to a PC, connect to VPN, and sign in to Office 365 in a browser. Phone sign-in uses Bluetooth, which means no need to wait for a phone call -- just unlock the phone and tap the app.
![Sign in to a device](images/phone-signin-menu.png)
> [!NOTE]
> Phone sign-in is currently limited to select Technology Adoption Program (TAP) participants.
You can create a Group Policy or mobile device management (MDM) policy that will allow users to sign in to a work PC or their company's VPN using the credentials stored on their Windows 10 phone.
## Prerequisites
- Both phone and PC must be running Windows 10, version 1607.
- The PC must be running Windows 10 Pro, Enterprise, or Education
- Both phone and PC must have Bluetooth.
- The **Microsoft Authenticator** app must be installed on the phone.
- The PC must be joined to an Active Directory domain that is connected to an Azure Active Directory (Azure AD) domain, or the PC must be joined to Azure AD.
- The phone must be joined to Azure AD or have a work account added.
- The VPN configuration profile must use certificate-based authentication.
## Set policies
To enable phone sign-in, you must enable the following policies using Group Policy or MDM.
- Group Policy: **Computer Configuration** or **User Configuration** > **Policies** > **Administrative Templates** > **Windows Components** > **Windows Hello for Business**
- Enable **Use Windows Hello for Business**
- Enable **Phone Sign-in**
- MDM:
- Set **UsePassportForWork** to **True**
- Set **Remote\UseRemotePassport** to **True**
## Configure VPN
To enable phone sign-in to VPN, you must enable the [policy](#set-policies) for phone sign-in and ensure that VPN is configured as follows:
- For inbox VPN, set up the VPN profile with Extensible Authentication Protocol (EAP) with the **Smart card or other certificate (TLS)** EAP type, also known as EAP-Transport Level Security (EAP-TLS). To exclusively access the VPN certificates on the phone, in the EAP filtering XML, add either **EKU** or **Issuer** (or both) filtering to make sure it picks only the Remote NGC certificate.
- For a Universal Windows Platform (UWP) VPN plug-in, add filtering criteria based on the 3rd party mechanism for the Remote NGC Certificate.
## Get the app
If you want to distribute the **Microsoft Authenticator** app, your organization must have set up Windows Store for Business, with Microsoft added as a [Line of Business (LOB) publisher](../manage/working-with-line-of-business-apps.md).

# Windows Hello errors during PIN creation
**Applies to**
- Windows 10
- Windows 10 Mobile
When you set up Windows Hello in Windows 10, you may get an error during the **Create a PIN** step. This topic lists some of the error codes with recommendations for mitigating the problem. If you get an error code that is not listed here, contact Microsoft Support.
## Where is the error code?
The following image shows an example of an error during **Create a PIN**.
![](images/pinerror.png)
## Error mitigations
When a user encounters an error when creating the work PIN, advise the user to try the following steps. Many errors can be mitigated by one of these steps.
1. Try to create the PIN again. Some errors are transient and resolve themselves.
2. Sign out, sign in, and try to create the PIN again.
3. Reboot the device and then try to create the PIN again.
4. Unjoin the device from Azure Active Directory (Azure AD), rejoin, and then try to create the PIN again. To unjoin a desktop PC, go to **Settings** &gt; **System** &gt; **About** and select **Disconnect from organization**. To unjoin a device running Windows 10 Mobile, you must [reset the device](https://go.microsoft.com/fwlink/p/?LinkId=715697).
5. On mobile devices, if you are unable to setup a PIN after multiple attempts, reset your device and start over. For help on how to reset your phone go to [Reset my phone](https://go.microsoft.com/fwlink/p/?LinkId=715697).
If the error occurs again, check the error code against the following table to see if there is another mitigation for that error. When no mitigation is listed in the table, contact Microsoft Support for assistance.

Configuration Manager and MDM provide the ability to manage Windows Hello for Business policy and to deploy and manage certificates protected by Windows Hello for Business.
Azure AD provides the ability to register devices with your enterprise and to provision Windows Hello for Business for organization accounts.
## Windows Hello for BYOD
Windows Hello can be managed on personal devices that your employees use for work purposes using MDM. On personal devices, users can create a personal Windows Hello PIN for unlocking the device and used this PIN for access to work resources.
The PIN is managed using the same Windows Hello for Business policies that you can use to manage Windows Hello for Business on organization-owned devices. The PIN can also be managed using DeviceLock policy. DeviceLock policy can be used to control length, complexity, history, and expiration requirements and can be configured using the [Policy configuration service provider](https://go.microsoft.com/fwlink/p/?LinkID=623244).

# Manage identity verification using Windows Hello for Business
**Applies to**
- Windows 10
- Windows 10 Mobile
In Windows 10, Windows Hello for Business replaces passwords with strong two-factor authentication on PCs and mobile devices. This authentication consists of a new type of user credential that is tied to a device and a biometric or PIN.
>[!NOTE]
> When Windows 10 first shipped, it included Microsoft Passport and Windows Hello, which worked together to provide multi-factor authentication. To simplify deployment and improve supportability, Microsoft has combined these technologies into a single solution under the Windows Hello name. Customers who have already deployed these technologies will not experience any change in functionality. Customers who have yet to evaluate Windows Hello will find it easier to deploy due to simplified policies, documentation, and semantics.
Hello addresses the following problems with passwords:
- Passwords can be difficult to remember, and users often reuse passwords on multiple sites.
- Server breaches can expose symmetric network credentials.
- Passwords can be subject to [replay attacks](https://go.microsoft.com/fwlink/p/?LinkId=615673).
- Users can inadvertently expose their passwords due to [phishing attacks](https://go.microsoft.com/fwlink/p/?LinkId=615674).
Hello lets users authenticate to:
- a Microsoft account.
- an Active Directory account.
- a Microsoft Azure Active Directory (Azure AD) account.
- Identity Provider Services or Relying Party Services that support [Fast ID Online (FIDO) v2.0](https://go.microsoft.com/fwlink/p/?LinkId=533889) authentication
After an initial two-step verification of the user during enrollment, Hello is set up on the user's device and the user is asked to set a gesture, which can be a biometric, such as a fingerprint, or a PIN. The user provides the gesture to verify their identity. Windows then uses Hello to authenticate users and help them to access protected resources and services.
As an administrator in an enterprise or educational organization, you can create policies to manage Hello use on Windows 10-based devices that connect to your organization.
## The difference between Windows Hello and Windows Hello for Business
- Individuals can create a PIN or biometric gesture on their personal devices for convenient sign-in. This use of Hello provides a layer of protection by being unique to the device on which it is set up, however it is not backed by certificate-based authentication.
- Windows Hello for Business, which is configured by Group Policy or MDM policy, uses key-based or certificate-based authentication.
- Currently Active Directory accounts using Windows Hello are not backed by key-based or certificate-based authentication. Support for key-based or certificate-based authentication is on the roadmap for a future release.
## Benefits of Windows Hello
Reports of identity theft and large-scale hacking are frequent headlines. Nobody wants to be notified that their user name and password have been exposed.
You may wonder [how a PIN can help protect a device better than a password](why-a-pin-is-better-than-a-password.md). Passwords are shared secrets; they are entered on a device and transmitted over the network to the server. An intercepted account name and password can be used by anyone. Because they're stored on the server, a server breach can reveal those stored credentials.
In Windows 10, Hello replaces passwords. The Hello provisioning process creates a cryptographic key pair bound to the Trusted Platform Module (TPM), if a device has a TPM, or in software. Access to these keys and obtaining a signature to validate user possession of the private key is enabled only by the PIN or biometric gesture. The two-step verification that takes place during Hello enrollment creates a trusted relationship between the identity provider and the user when the public portion of the public/private key pair is sent to an identity provider and associated with a user account. When a user enters the gesture on the device, the identify provider knows from the combination of Hello keys and gesture that this is a verified identity and provides an authentication token that allows Windows 10 to access resources and services. In addition, during the registration process, the attestation claim is produced for every identity provider to cryptographically prove that the Hello keys are tied to TPM. During registration, when the attestation claim is not presented to the identity provider, the identity provider must assume that the Hello key is created in software.
![how authentication works in windows hello](images/authflow.png)
Imagine that someone is looking over your shoulder as you get money from an ATM and sees the PIN that you enter. Having that PIN won't help them access your account because they don't have your ATM card. In the same way, learning your PIN for your device doesn't allow that attacker to access your account because the PIN is local to your specific device and doesn't enable any type of authentication from any other device.
Hello helps protect user identities and user credentials. Because no passwords are used, it helps circumvent phishing and brute force attacks. It also helps prevent server breaches because Hello credentials are an asymmetric key pair, which helps prevent replay attacks when these keys are protected by TPMs.
Hello also enables Windows 10 Mobile devices to be used as [a remote credential](prepare-people-to-use-microsoft-passport.md#bmk-remote) when signing into Windows 10 PCs. During the sign-in process, the Windows 10 PC can connect using Bluetooth to access Hello on the user’s Windows 10 Mobile device. Because users carry their phone with them, Hello makes implementing two-factor authentication across the enterprise less costly and complex than other solutions.
> [!NOTE]
>  Phone sign-in is currently limited to select Technology Adoption Program (TAP) participants.
 
## How Windows Hello for Business works: key points
- Hello credentials are based on certificate or asymmetrical key pair. Hello credentials are bound to the device, and the token that is obtained using the credential is also bound to the device.
- Identify provider (such as Active Directory, Azure AD, or a Microsoft account) validates user identity and maps Hello's public key to a user account during the registration step.
- Keys can be generated in hardware (TPM 1.2 or 2.0 for enterprises, and TPM 2.0 for consumers) or software, based on the policy.
- Authentication is the two-factor authentication with the combination of a key or certificate tied to a device and something that the person knows (a PIN) or something that the person is (Windows Hello). The Hello gesture does not roam between devices and is not shared with the server; it is stored locally on a device.
- Private key never leaves a device. The authenticating server has a public key that is mapped to the user account during the registration process.
- PIN entry and biometric gesture both trigger Windows 10 to verify the user's identity and authenticate using Hello keys or certificates.
- Personal (Microsoft account) and corporate (Active Directory or Azure AD) accounts use a single container for keys. All keys are separated by identity providers' domains to help ensure user privacy.
- Certificate private keys can be protected by the Hello container and the Hello gesture.
## Comparing key-based and certificate-based authentication
Windows Hello for Business can use either keys (hardware or software) or certificates with keys in hardware or software to confirm identity. Enterprises that have a public key infrastructure (PKI) for issuing and managing certificates can continue to use PKI in combination with Hello. Enterprises that do not use PKI or want to reduce the effort associated with managing certificates can rely on key-based credentials for Hello.
Hardware-based keys, which are generated by TPM, provide the highest level of assurance. When the TPM is manufactured, an Endorsement Key (EK) certificate is resident in the TPM. This EK certificate creates a root trust for all other keys that are generated on this TPM.
EK certification is used to generate an attestation identity key (AIK) certificate issued by a Microsoft certificate authority. This AIK certificate can be used as an attestation claim to prove to identity providers that the Hello keys are generated on the same TPM. The Microsoft certificate authority (CA) generates the AIK certificate per device, per user, and per IDP to help ensure that user privacy is protected.
When identity providers such as Active Directory or Azure AD enroll a certificate in Hello, Windows 10 will support the same set of scenarios as a smart card. When the credential type is a key, only key-based trust and operations will be supported.

# Prepare people to use Windows Hello
**Applies to**
- Windows 10
- Windows 10 Mobile
When you set a policy to require Windows Hello for Business in the workplace, you will want to prepare people in your organization by explaining how to use Hello.
After enrollment in Hello, users should use their gesture (such as a PIN or fingerprint) for access to corporate resources. Their gesture is only valid on the enrolled device.
Although the organization may require users to change their Active Directory or Azure Active Directory (AD) account password at regular intervals, changes to their passwords have no effect on Hello.
People who are currently using virtual or physical smart cards for authentication can use their virtual smart card to verify their identity when they set up Hello.
## On devices owned by the organization
When someone sets up a new device, they are prompted to choose who owns the device. For corporate devices, they select **This device belongs to my organization**.
![who owns this pc](images/corpown.png)
Next, they select a way to connect. Tell the people in your enterprise which option they should pick here.

They sign in, and are then asked to verify their identity. People have options to choose from, such as a text message, phone call, or authentication app. After verification, they create their PIN. The **Create a PIN** screen displays any complexity requirements that you have set, such as minimum length.
After Hello is set up, people use their PIN to unlock the device, and that will automatically log them on.
## On personal devices
People who want to access work resources on their personal devices can add a work or school account in **Settings** &gt; **Accounts** &gt; **Work or school**, and then sign in with work credentials. The person selects the method for receiving the verification code, such as text message or email. The verification code is sent and the person then enters the verification code. After verification, the person enters and confirms new PIN. The person can access any token-based resource using this device without being asked for credentials.
People can go to **Settings** &gt; **Accounts** &gt; **Work or school**, select the work account, and then select **Unjoin** to remove the account from their device.
## Using Windows Hello and biometrics
If your policy allows it, people can use biometrics (fingerprint, iris, and facial recognition) with Windows Hello for Business, if the hardware supports it.

## <a href="" id="bmk-remote"></a>Use a phone to sign in to a PC or VPN
If your enterprise enables phone sign-in, users can pair a phone running Windows 10 Mobile to a PC running Windows 10 and then use an app on the phone to sign in to the PC using their Windows Hello credentials.
> [!NOTE]
> Phone sign-in is currently limited to select Technology Adoption Program (TAP) participants.
 
**Prerequisites:**
- Both phone and PC must be running Windows 10, version 1607.
- The PC must be running Windows 10 Pro, Enterprise, or Education
- Both phone and PC must have Bluetooth.
- The **Microsoft Authenticator** app must be installed on the phone.
- The PC must be joined to an Active Directory domain that is connected to an Azure Active Directory (Azure AD) domain, or the PC must be joined to Azure AD.
- The phone must be joined to Azure AD or have a work account added.
- The VPN configuration profile must use certificate-based authentication.
**Pair the PC and phone**
1. On the PC, go to **Settings** &gt; **Devices** &gt; **Bluetooth**. Tap the name of the phone and then tap **Pair** to begin pairing.
![bluetooth pairing](images/btpair.png)
2. On the phone, go to **Settings** &gt; **Devices** &gt; **Bluetooth**, and verify that the passcode for **Pairing accessory** on the phone matches the passcode displayed on the PC, and then tap **ok**.
![bluetooth pairing passcode](images/bt-passcode.png)
3. On the PC, tap **Yes**.
**Sign in to PC using the phone**
1. Open the **Microsoft Authenticator** app, choose your account, and tap the name of the PC to sign in to.
> **Note: **  The first time that you run the **Microsoft Authenticator** app, you must add an account.
![select a device](images/phone-signin-device-select.png)
 
2. Enter the work PIN that you set up when you joined the phone to the cloud domain or added a work account.
**Connect to VPN**
You simply connect to VPN as you normally would. If the phone's certificates are being used, a notification will be pushed to the phone asking if you approve. If you click **allow** in the notification, you will be prompted for your PIN. After you enter your PIN, the VPN session will connect.

# Why a PIN is better than a password
**Applies to**
- Windows 10
- Windows 10 Mobile
Windows Hello in Windows 10 enables users to sign in to their device using a PIN. How is a PIN different from (and better than) a password?
On the surface, a PIN looks much like a password. A PIN can be a set of numbers, but enterprise policy might allow complex PINs that include special characters and letters, both upper-case and lower-case. Something like **t758A!** could be an account password or a complex Hello PIN. It isn't the structure of a PIN (length, complexity) that makes it better than a password, it's how it works.
## PIN is tied to the device
One important difference between a password and a Hello PIN is that the PIN is tied to the specific device on which it was set up. That PIN is useless to anyone without that specific hardware. Someone who steals your password can sign in to your account from anywhere, but if they steal your PIN, they'd have to steal your physical device too!
Even you can't use that PIN anywhere except on that specific device. If you want to sign in on multiple devices, you have to set up Hello on each device.
## PIN is local to the device
A password is transmitted to the server -- it can be intercepted in transmission or stolen from a server. A PIN is local to the device -- it isn't transmitted anywhere and it isn't stored on the server.
When the PIN is created, it establishes a trusted relationship with the identity provider and creates an asymmetric key pair that is used for authentication. When you enter your PIN, it unlocks the authentication key and uses the key to sign the request that is sent to the authenticating server.
> **Note:**  For details on how Hello uses asymetric key pairs for authentication, see [Microsoft Passport guide](https://go.microsoft.com/fwlink/p/?LinkId=691928).
 
## PIN is backed by hardware
The Hello PIN is backed by a Trusted Platform Module (TPM) chip, which is a secure crypto-processor that is designed to carry out cryptographic operations. The chip includes multiple physical security mechanisms to make it tamper resistant, and malicious software is unable to tamper with the security functions of the TPM. All Windows 10 Mobile phones and many modern laptops have TPM.
User key material is generated and available within the Trusted Platform Module (TPM) of the user device, which protects it from attackers who want to capture the key material and reuse it. Because Hello uses asymmetrical key pairs, users credentials can’t be stolen in cases where the identity provider or websites the user accesses have been compromised.
The TPM protects against a variety of known and potential attacks, including PIN brute-force attacks. After too many incorrect guesses, the device is locked.
## PIN can be complex
The Windows Hello for Business PIN is subject to the same set of IT management policies as a password, such as complexity, length, expiration, and history. Although we generally think of a PIN as a simple four-digit code, administrators can set [policies](implement-microsoft-passport-in-your-organization.md) for managed devices to require a PIN complexity similar to a password. You can require or block: special characters, uppercase characters, lowercase characters, and digits.
## What if someone steals the laptop or phone?
To compromise a Windows Hello credential that TPM protects, an attacker must have access to the physical device, and then must find a way to spoof the user’s biometrics or guess his or her PIN—and all of this must be done before TPM anti-hammer capabilities lock the device.
You can provide additional protection for laptops that don't have TPM by enablng BitLocker and setting a policy to limit failed sign-ins.
**Configure BitLocker without TPM**
1. Use the Local Group Policy Editor (gpedit.msc) to enable the following policy:
**Computer Configuration** &gt; **Administrative Templates** &gt; **Windows Components** &gt; **BitLocker Drive Encryption** &gt; **Operating System Drives** &gt; **Require additional authentication at startup**
2. In the policy option, select **Allow BitLocker without a compatible TPM**, and then click **OK.**
3. Go to Control Panel &gt; **System and Security** &gt; **BitLocker Drive Encryption** and select the operating system drive to protect.
**Set account lockout threshold**
1. Use the Local Group Policy Editor (gpedit.msc) to enable the following policy:
**Computer Configuration** &gt;**Windows Settings** ?**Security Settings** &gt;**Account Policies** &gt; **Account Lockout Policy** &gt; **Account lockout threshold**
2. Set the number of invalid logon attempts to allow, and then click OK.
## Why do you need a PIN to use biometrics?
Windows Hello enables biometric sign-in for Windows 10: fingerprint, iris, or facial recognition. When you set up Windows Hello, you're asked to create a PIN first. This PIN enables you to sign in using the PIN when you can’t use your preferred biometric because of an injury or because the sensor is unavailable or not working properly.
If you only had a biometric sign-in configured and, for any reason, were unable to use that method to sign in, you would have to sign in using your account and password, which doesn't provide you the same level of protection as Hello.

Using this feature, you can turn on a global setting that stops your employees from loading untrusted fonts processed using the Graphics Device Interface (GDI) onto your network. Untrusted fonts are any font installed outside of the %windir%/Fonts directory. Blocking untrusted fonts helps prevent both remote (web-based or email-based) and local EOP attacks that can happen during the font file-parsing process. |

If the app isn’t trusted it can’t run, period. It also means that even if an attacker manages to get control of the Windows kernel, he or she will be much less likely to be able to run malicious executable code after the computer restarts because of how decisions are made about what can run and when. |
