        <p class="text-gray-600 dark:text-gray-400 text-sm leading-relaxed">
          Two-Factor Authentication (2FA) adds an extra layer of security to your account.
          It requires both your password and a second piece of information (like a code from your phone)
          to verify your identity before granting access.
        </p>
        <p class="text-gray-600 dark:text-gray-400 text-sm leading-relaxed mt-2">
          This protects your account even if your password is stolen.
