在浏览互联网时，强大的互联网安全至关重要，因为计算机系统极易受到安全攻击。您的浏览器是存储密码等敏感数据的最易受攻击的组件。黑客和未经授权的用户不断威胁，他们可以登录您的帐户以访问私人数据并窃取您的银行详细信息等敏感信息。需要构建一个强大的安全浏览器来防止黑客等互联网威胁、恶意软件、病毒等。

如今，仅使用密码保护您的数据是不够的，您可能希望使用两步验证^{(Two-step authentication)}来构建强大的数据安全系统。基本上，两步验证要求用户使用传统的密码或登录方法来确认身份，并使用第二种验证方法来增加安全性。两步身份验证是多因素身份验证的子集，其中通过使用多个身份验证因素确认用户的身份来确保安全性。这是防止未经授权的用户访问私人数据并因此建立强大的在线数据隐私的最安全方法。

Mozilla为^(Mozilla)Firefox帐户持有人推出了两步验证。为Firefox^(Firefox)帐户设置两步验证是一个简单的过程，它利用了一种称为TOTP（基于时间的一次性密码）^{(TOTP (Time-based One-Time Password))}的著名算法。您可以使用Google Authenticator、Duo、Authy等验证器应用程序，通过扫描^(Authy)Firefox浏览器页面上生成的二维码，在智能手机上生成TOTP码。^(TOTP)在本文中，我们将详细解释如何在Mozilla Firefox for Windows系统中设置双重身份验证。

在Firefox^(Firefox)   for Windows 10中开启两步验证

更改 Firefox 选项^{(Change Firefox Options)}

打开Firefox 浏览器^{(Firefox browser)}并导航到选项。^{(Options. )}转到Firefox 帐户^{(Firefox Account)}，然后单击管理帐户。^{(Manage account.)}

单击启用^{( Enable)}按钮进行两步验证。^{(Two-step authentication.)}

如果您没有看到两步验证部分，请在浏览器地址栏中输入“Two Step Authentication=true”并刷新页面。

获取身份验证应用程序^{(Get the authentication apps)}

选择要与Firefox浏览器一起使用的身份验证器应用程序。身份验证器应用程序用于生成TOTP（基于时间的一次性密码^{(One-Time Password)}）代码。您可以下载身份验证器应用程序，如Google Authenticator、Duo Mobile、Authy 2-Factor Authentication和其他最适合您的智能手机设备的知名应用程序。

身份验证应用程序可以安装在Android和 iOS 设备上。如果您使用的是Android设备，请在此处下载Google Authenticator应用程序。^(here.)Android 用户可以在此处下载Duo Mobile应用程序，并在此处^(here)下载Authy 2-Factor Authentication 。^(here.)如果您使用的是 iOS 设备，请在此处下载Google Authenticator应用程序。^(here.)iOS 用户可以在此处下载^(here)Duo Mobile应用程序和Authy 2-Factor Authentication应用程序。^(here.)

扫描二维码并生成 OTP 码^{(Scan the QR code and Generate the OTP code)}

在智能手机上打开下载的身份验证应用程序。

要生成安全码，请从您的智能手机拍摄QR 码^{(QR code)}的照片，以便扫描Firefox帐户页面上可见的 QR 码。

在Firefox 帐户配置文件的两步验证^{(Two-step authentication)}中输入安全代码。^{(security code)}

如果您在扫描二维码时遇到问题，可以选择手动设置安全码。只需单击“无法扫描代码”选项以手动设置安全代码。

在您的浏览器上启用两步验证后，用户必须在每次登录时使用智能手机上的验证器应用程序生成TOTP安全码，同时输入常规密码以确认身份。

此外，建议您下载恢复代码并将其存储在安全位置，以防手机丢失。^{(Additionally, it is advisable to download and store the recovery code in the safe location in case if your phone is lost.)}

Enable Two Step Authentication in Mozilla Firefox for Windows 10

A strong internet security is essential whіle browsing through the internet as the computer system is highly vulnerable to security attacks.
