When an attacker steals the password database for a site that you use (like <a { $url_linkedin }>LinkedIn</a> or <a { $url_yahoo }>Yahoo</a>), there’s nothing you can do but change your password for that site. That’s bad, but the damage can be much worse if you’ve re-used that password with other websites — then the attacker can access your accounts on those sites as well. To keep the damage contained, <strong>always use different passwords for different websites.</strong>
攻击者窃取您所使用网站（例如 <a { $url_linkedin }>LinkedIn</a> 或 <a { $url_yahoo }>Yahoo</a>）的密码数据库后，您能做的只有更改您用于该网站的密码。这固然很糟糕，但如果您在其他网站上也使用同样的密码，损失可能会更大，攻击者将可以访问您在其他网站的账号。为了减少损失，<strong>请始终对不同的网站使用不同的密码。</strong>
