如果您的密码错误，您的系统就有风险。微软(Microsoft)没有依赖过时的安全性，而是通过Windows 10 May 2019更新引领潮流，该更新增加了对完全无密码登录的支持。
我们之前讨论过如何在没有密码的情况下使用 Windows(how to use Windows without a password)，但这不是无密码登录的意义所在。Windows无密码登录不是使用密码，而是让您使用备用安全方法登录。要使用该功能，您需要确保已安装Windows 10 版本 1903。
在 Windows 10 上创建无密码登录(Creating a Passwordless Login On Windows 10)
如果您安装了Windows 10版本 1903，则可以使用您的手机号码创建无密码用户帐户。不幸的是，您无法将现有用户帐户转换为这种无密码登录，尽管其他类型的Windows 10无密码登录可用。
创建完全无密码的用户帐户似乎仅适用于Windows 10 Home，目前不适用于其他版本的Windows 10。您仍然可以仅使用您的手机号码 创建Microsoft帐户，但您可能需要先为您的帐户添加密码。(Microsoft)
完成此操作后，您可以使用另一种形式的无密码登录。为此，请前往现有用户帐户的可用无密码登录方法(Available Passwordless Sign-In Methods for Existing User Accounts)部分。
- 首先，您需要前往您的Windows 10帐户设置区域。右键单击您的Windows 开始(Windows Start)菜单按钮，然后单击设置(Settings)。
- 在Windows 设置(Windows Settings)菜单中，单击帐户(Accounts)。
- 在“帐户(Accounts)”菜单的左侧边栏中，单击“家庭和其他用户”。(Family & other users.)
- 在家庭和其他用户下，单击将其他人添加到这台电脑。(Add someone else to this PC.)
- 当您要创建无密码登录时，在出现的Microsoft登录菜单中，输入您的电话号码，然后单击下一步(Next)。如果您的号码未附加到帐户，您需要点击注册一个新(Sign up for a new one)号码。
一旦您的帐户与您的 Windows 10 安装相匹配，您就可以使用SMS、Microsoft Authenticator应用程序或使用下面提到的方法之一登录而无需密码。
现有用户帐户可用的无密码 Windows 登录方法(Available Passwordless Windows Login Methods For Existing User Accounts)
如果您已在Windows上登录用户帐户，则可以更改登录选项以完全绕过密码。
Windows 10 允许您使用PIN码、USB安全密钥、“图片密码”（您可以在其中选择您最喜欢的图片进行登录）或使用您的面部（类似于 Apple 的Face ID）登录。
如果您需要更改登录方式或访问您的帐户设置，您仍需要不时使用您的密码。如果您启用了双因素身份验证，您还需要让您的手机（使用SMS或Microsoft Authenticator应用程序）可供您使用。
某些(Certain)方法，例如指纹或面部登录方法，还需要您的 PC 具有指纹扫描仪或合适的网络摄像头。
要开始更改您的登录方法，不再使用密码：
- 如上所述，前往您的 Windows 10 帐户设置区域。
- 右键单击 Windows 开始菜单按钮，单击设置(Settings)，然后单击帐户(Accounts)。在此处，单击侧面菜单中的登录选项(Sign-in options)。
- 选择您选择的登录选项。例如，如果您想使用PIN而不是密码，请点击Windows Hello PIN，然后单击添加。(Add.)如果您的设备上有指纹扫描仪，则可以选择Windows Hello 指纹(Windows Hello Fingerprint)。
- 按照每个选项的说明进行操作。按Windows key + L锁定屏幕并测试新的登录方法。
无密码锁定和解锁(Passwordless Locking & Unlocking)
您还可以将您的 PC 设置为自动锁定和解锁您的 PC，而无需使用您的密码或上面列出的任何登录方法。如果您在公共场所从 PC 来回移动，或者如果您不想在锁定 PC 时继续使用 PC 的安全性，这将非常有用。
您需要使用蓝牙(Bluetooth) 将您的 PC 与适当的设备配对。
- 在登录选项(Sign-in options )菜单中，在各种登录选项下方，您会看到动态锁定(Dynamic Lock)选项。单击允许 Windows 在您离开时自动锁定您的设备(Allow Windows to lock your device automatically when you’re away)复选框。
- 您需要启用蓝牙(Bluetooth)才能使其正常工作。如果设备已与您的“解锁设备”（例如智能手机）配对，请单击扫描设备。(Scan for device)如果您的 PC 未与“解锁设备”配对，请单击蓝牙和其他设备。(Bluetooth & other devices.)
- 确保(Make)在您的“解锁设备”上启用了蓝牙(Bluetooth)，并且两个设备都是可发现的。单击添加蓝牙或其他设备(Add Bluetooth or other device)开始配对。
- 单击添加设备(Add a device)列表中的蓝牙。(Bluetooth)
一旦您的设备与您的“解锁设备”配对，您的 PC 将在蓝牙范围内时自动解锁或在蓝牙(Bluetooth)范围(Bluetooth)外时解锁，从而提高 PC 的整体安全性。
在 Window 10 上使用无密码登录(Using Passwordless Logins On Window 10)
如果您最终忘记了密码，您也可以绕过您的 Windows 10 密码(bypass your Windows 10 password)，但这不是最好的方法，因为它会使您的 PC 没有任何安全性。
如果您切换到这些无密码方法之一，您将无需担心将来忘记密码。您可以改用您的生物识别、SMS消息或单独的USB安全密钥来登录您的 Windows 10 电脑。
How To Create a Passwordless Login On Windows 10
If your pasѕword is poor, your system is at risk. Rather than rely on outdated security, Microsoft is leading the way with the Windows 10 May 2019 update, which added support for completely passwordless logins.
We’ve talked before about how to use Windows without a password, but that isn’t what passwordless logins are about. Rather than using a password, Windows passwordless logins let you sign in using alternate security methods. To use the feature, you’ll need to make sure you have Windows 10 version 1903 installed.
Creating a Passwordless Login On Windows 10
If you have Windows 10 version 1903 installed, you can create a passwordless user account using your cell phone number. Unfortunately, you can’t convert an existing user account to this kind of passwordless login, although other types of passwordless logins for Windows 10 are available.
Creating a completely passwordless user account seems to only work on Windows 10 Home, and not other versions of Windows 10 at present. You can still create a Microsoft account using just your cell phone number, but you may need to add a password to your account first.
Once you do this, you can use another form of passwordless sign-in. To do that, head to the Available Passwordless Sign-In Methods for Existing User Accounts section.
- To start, you need to head to your Windows 10 accounts settings area. Right-click your Windows Start menu button and click Settings.
- In the Windows Settings menu, click Accounts.
- In the left-hand sidebar of the Accounts menu, click Family & other users.
- Under Family & other users, click Add someone else to this PC.
- As you want to create a passwordless login, in the Microsoft sign-in menu that appears, type your phone number, then click Next. If your number isn’t attached to an account, you’ll need to click Sign up for a new one.
- Follow the on-screen instructions to create your account.
Once your account is matched with your Windows 10 installation, you’ll be able to sign in without a password using SMS, the Microsoft Authenticator app, or by using one of the methods mentioned below.
Available Passwordless Windows Login Methods For Existing User Accounts
If you’re already signed in to a user account on Windows, you can change your sign-in option to bypass your password completely.
Windows 10 lets you sign in using a PIN code, a USB security key, a “picture password” where you select your favorite picture to sign in with, or by using your face (similar to Apple’s Face ID).
You’ll still need to use your password from time to time if you need to change your sign-in method or access your account settings. If you have two-factor authentication enabled, you’ll also need to have your phone (with SMS or the Microsoft Authenticator app) available to you.
Certain methods, like the fingerprint or face sign-in methods, also require your PC to have a fingerprint scanner or suitable webcam.
To begin changing your sign-in method away from using a password:
- As above, head to your Windows 10 account settings area.
- Right-click your Windows Start menu button, click Settings, then click Accounts. From here, click Sign-in options in the side menu.
- Select your chosen sign-in option. For instance, if you want to use a PIN instead of a password, tap Windows Hello PIN and then click Add. If you have a fingerprint scanner on your device, you can choose Windows Hello Fingerprint.
- Follow the instructions for each option. Press Windows key + L to lock your screen and test out your new sign-in methods.
Passwordless Locking & Unlocking
You can also set your PC to automatically lock and unlock your PC without using your password or any of the sign-in methods listed above. This is useful if you’re moving back and forth from your PC in a public place, or if you don’t want to keep using your PC’s security whenever you lock your PC.
You need to pair your PC to an appropriate device, using Bluetooth.
- In the Sign-in options menu, below the various sign-in options, you’ll see an option for Dynamic Lock. Click on the Allow Windows to lock your device automatically when you’re away checkbox.
- You’ll need Bluetooth to be enabled for this to work. Click Scan for device if it’s already paired with your “unlocking device”, such as your smartphone. If your PC isn’t paired with your “unlocking device”, click Bluetooth & other devices.
- Make sure Bluetooth is enabled on your “unlocking device”, and that both devices are discoverable. Click Add Bluetooth or other device to begin pairing them.
- Click Bluetooth in the Add a device list.
Once your device is paired with your “unlocking device”, your PC will automatically unlock when it is in Bluetooth range or unlock when it is out of Bluetooth range, improving the security of your PC overall.
Using Passwordless Logins On Window 10
You can also bypass your Windows 10 password if you end up forgetting your password, but this isn’t the best method, as it leaves your PC without any kind of security.
If you switch to one of these passwordless methods, you won’t need to worry about forgetting your password in the future. You can use your biometrics, an SMS message, or a separate USB security key to sign in to your Windows 10 PC instead.
