保护您的在线帐户免遭入侵的最佳方法之一是使用双重身份验证 (2FA)。这为登录过程增加了第二层，要求您使用一次性生成的代码（通常在您的智能手机上创建）使用Google Authenticator等工具成功登录。
当然，如果您的智能手机确实安装了Google Authenticator ，那就是这样。如果您不这样做，那么您的选择是有限的，但是您可以在您的 PC 上使用Google Authenticator，而无需其他设备。如果您想知道如何在Windows 10上使用(Windows 10)Google Authenticator，这就是您所需要的。
生成 Google Authenticator 密码(Generating the Google Authenticator Secret Code)
如果用户名和密码在网上泄露(username and password is leaked online)，您的帐户将面临风险。在这一点上，即使使用密码管理器(password manager)也无济于事——您需要更改任何因违规而受损的密码。
为帮助解决此问题，您可以将您的在线帐户链接到双重身份验证服务，例如Google Authenticator。这会生成一个一次性密码 ( OTP ) 以成功登录Google和其他在线服务。
如果黑客没有您的 2FA 凭据，密码是否被破坏也没关系。2FA 增加了另一层安全性。要生成代码，您需要使用第三方应用在 Windows PC 上设置Google Authenticator ，并插入与您的(Google Authenticator)Google帐户匹配的密码。
密码就像一个主密码 - 没有它，生成的代码将无法完成 2FA 登录。此代码仅适用于您的Google帐户登录，但您需要类似的代码来链接您的Windows PC 上带有 2FA 应用程序的其他在线服务。
- 要查找您的Google帐户的密码，请打开Google 帐户网站(Google account website)。在左侧菜单中，选择安全(Security)。
- 在Google帐户网站的(Google)安全(Security)区域中，向下滚动到登录 Google(Signing in to Google )部分，然后选择两步验证(2-Step Verification )选项。此时您可能需要重新登录。
- 如果您之前尚未在移动设备上启用 2FA，则需要按照两步验证(2-Step Verification )页面上的屏幕说明进行操作。完成后，向下滚动到Authenticator 应用(Authenticator app )部分，然后选择设置(Set Up)开始。
- 在弹出菜单中，选择Android或iPhone，因为选项无关紧要。选择下一步(Next )继续。
- 在下一阶段，您将看到通常需要扫描的 QR 码。但是，您不会这样做，因此请选择无法扫描？(Can’t Scan It? )选项。
- 您的Google帐户密码将显示在下面的框中，由 32 个字母和数字组成。写下来或制作合适的副本，然后选择下一步(Next)继续。保持此页面打开，因为之后您将需要它来完成设置过程。
保存密码后，您需要在 PC 上安装 2FA 应用程序才能继续。
安装适用于 Windows 10 的两因素身份验证应用程序(Installing a Two Factor Authentication App for Windows 10)
不幸的是，很少有应用程序可以将Google Authenticator支持扩展到Windows 10。WinAuth是一个例外，虽然它仍然很受欢迎，但 WinAuth(WinAuth)不再处于积极开发中，因此我们不能保证它继续按预期作为Google Authenticator替代品工作。
由于可用的桌面应用程序很少，最好的替代品可以在Microsoft Store中找到。一个例子是WinOTP Authenticator ，这是一款可以通过(WinOTP Authenticator)Microsoft Store正式安装的开源 2FA 应用程序，尽管可以在开发人员的GitHub页面上查看源代码。

但是，您需要记住，每个帐户只允许使用一个Authenticator应用程序。(Authenticator)如果您想在Windows上使用(Windows)Google Authenticator，此后您将无法在Android或 iPhone 上使用(Android)Google Authenticator应用程序登录您的Google帐户。
如果您还没有，建议您在所有重要帐户上设置双重身份验证，以帮助改善您的在线隐私(improve your privacy online)。这包括在社交媒体上设置 2FA，(setting up 2FA on social media)以帮助您的帐户免受可能危及您身份的黑客的攻击。
How to Use Google Authenticator on Windows 10
One of the best ways to protect your online accounts from being compromised iѕ to use two-factor authentication (2FA). This adds a second layer to the sign-in process, requiring you tо use a one-use only generatеd code (usually created on your smartрhone) to sign in successfully υsing tools like Google Authenticator.
That is, of course, if you actually have a smartphone with Google Authenticator installed. If you don’t, then your options are limited, but it is possible to use Google Authenticator on your PC without requiring another device. If you want to know how to use Google Authenticator on Windows 10, here’s what you’ll need.
Generating the Google Authenticator Secret Code
If a username and password is leaked online, your account is at risk. Even using a password manager won’t help you at this point—you’ll need to change any passwords that are compromised by a breach.
To help overcome this issue, you can link your online accounts to a two-factor authentication service like Google Authenticator. This generates a one-time password (OTP) to successfully sign in to Google and other online services.
It doesn’t matter if a password is breached if the hacker doesn’t have your 2FA credentials. 2FA adds another layer of security. To generate the codes, you’ll need to set up Google Authenticator on your Windows PC using a third-party app and insert the secret code that matches your Google account.
The secret code is like a master password—without it, the codes being generated won’t work to complete a 2FA sign in. This code will only work for your Google account sign-in, but you’ll need similar codes to link your other online services with a 2FA app on your Windows PC.
- To find the secret code for your Google account, open the Google account website. In the left-hand menu, select Security.
- In the Security area of the Google account website, scroll down to the Signing in to Google section, then select the 2-Step Verification option. You may need to sign in again at this point.
- If you haven’t already enabled 2FA with a mobile device previously, you’ll need to follow the on-screen instructions to do so on the 2-Step Verification page. Once this is done, scroll down to the Authenticator app section, then select Set Up to begin.
- In the pop-up menu, select either Android or iPhone, as the option doesn’t matter. Select Next to continue.
- At the next stage, you’ll see a QR code that you’d typically need to scan. You won’t be doing this, however, so select the Can’t Scan It? option instead.
- The secret code for your Google account will appear in the box below, in a combination of 32 letters and numbers. Write this down or make a suitable copy of it, then select Next to continue. Keep this page open, as you’ll need it to complete the setup process afterwards.
Once you’ve saved the secret code, you’ll need to install a 2FA app on your PC to proceed.
Installing a Two Factor Authentication App for Windows 10
Unfortunately, there are few apps that exist for extending Google Authenticator support to Windows 10. WinAuth is one exception, and while it remains popular, WinAuth is no longer in active development, so we can’t guarantee that it continues to work as intended as a Google Authenticator alternative.
With few desktop apps available, the best alternatives are found in the Microsoft Store. One example is WinOTP Authenticator, an open-source 2FA app that can be installed officially through the Microsoft Store, although the source code is available for review on the developer’s GitHub page.
- To begin, download and install WinOTP Authenticator from the Microsoft Store. Once installed and opened, select the + (Add) icon at the bottom.
- You’ll need to save your Google account details here. Under Service, type Google. For Username, type your Google account email address. Finally, type your 32-digit secret code (with or without spaces) in the Code section, before selecting Save to save it to the app.
- If successful, a six-digit one-time passcode will appear at the top of the window. Return to the Google Authenticator app setup page (as described in the section above), or open the Google Authenticator App setup page directly, selecting the Set Up option in the Authenticator app section. Enter the six-digit code you see in the WinOTP app in the Google Authenticator app setup box, then select Verify to continue.
- If verified, WinOTP Authenticator will become the default Google Authentication app for your account. You can then use WinOTP to generate the 2FA codes you need to successfully sign in to your Google account (and into other Google services) in the future. If you want to remove the app at any point, press the remove icon next to the Authenticator app option listed in your Google account settings.
Installing a Two Factor Authentication Extension in Google Chrome
While WinOTP Authenticator offers a quick and easy way to sign in to Google services with two-factor authentication enabled, you can also set up a quick and easy-to-use 2FA app using a Google Chrome extension named Authenticator.
- To do this, you’ll need to open Google Chrome in your browser and install the Authenticator extension. As the simple name suggests, this extension allows you to quickly create OTP codes for two-factor authentication.
- Once installed, select the Authenticator extension icon (or select it from the Extensions menu in the top-right). From the drop-down menu, select the pencil icon.
- Press the + (plus) icon that appears in the card below to proceed.
- From the menu, select Manual Entry.
- You’ll need to provide your Google Authenticator secret code and account information here. Under Issuer, type Google. For Secret, type the 32-digit secret code for your Google account (as explained in the steps above). Select Advanced, then place your Google account username in the Username box, before selecting OK at the bottom to save your details.
- Once saved, select the Authenticator extension icon again to view your one-time passcode for your Google account.
Using Google Authenticator on Windows 10
Once a 2FA app is installed on your PC, you’ll be free to use Google Authenticator on Windows to sign into your Google account without needing a smartphone. This gives you a 2FA backup device, offering peace of mind that you won’t be locked out of your Google account, even if you lose your smartphone.
However, you’ll need to bear in mind that only one Authenticator app is allowed for each account. If you want to use Google Authenticator on Windows, you won’t be able to use the Google Authenticator app on Android or iPhone to sign in to your Google account after this point.
If you haven’t already, it’s advisable to set up two-factor authentication on all of your important accounts to help improve your privacy online. This includes setting up 2FA on social media to help keep your accounts free from hackers who could compromise your identity.
