在[[registrar|注册商]]处启用双因素认证(2FA)要求账户持有人在登录或执行敏感操作时,除密码外还需提供第二个验证因素——通常是认证应用的 TOTP 码、短信验证码或硬件安全密钥。启用 2FA 是防范账户劫持攻击的最有效手段之一,而账户劫持是未经授权的[[domain-transfer|域名转移]]和[[domain-hijacking|域名劫持]]最常见的途径。ICANN 的安全指南强烈建议所有注册商账户启用 2FA,尤其是管理高价值域名的账户。结合[[access-control-domain|基于角色的访问控制]]和强唯一密码,2FA 能显著提高攻击者的入侵门槛。
示例
After enabling 2FA with an authenticator app on your GoDaddy account, an attacker who phishes your password still cannot log in because they lack access to the rotating TOTP code on your phone.
