As Pew Research notes, your phone also connects to cell towers and Wi-Fi networks, and connection to these technologies allows tracking too.

皮尤研究中心指出，你的手机还会与手机信号塔和无线网络相连，从而导致数据被跟踪。

Myth 4. My password is enough to protect me

误解4：我的密码足以保护我。

Strong passwords are good, but security experts also recommend using two-factor authentication for account security. This means you must have a second login, like a security code sent to your phone, to sign into accounts. It prevents hackers from getting into your account, even if they know the password.

强大的密码很好，但安全专家也建议采用双重认证来保护账户安全。这意味着你必须二次登录，比如把验证码发送到你的手机，然后用验证码登录。这会阻止黑客盗走你的账户，就算他们知道密码也无计可施。

Just 10% of adults can identify one example of two-factor authentication.

只有10%的成年人能识别出一个双重认证的例子。

There is some good news from Pew, however: A vast majority of people can correctly identify a strong password, which includes one with random letters, numbers, and symbols. And 73% know using public Wi-Fi is bad for secure activities, such as paying bills online.

不过，皮尤研究中心也有一些好消息：绝大多数人都能正确识别出强大的密码，即随机的字母+数字+符号组合。73%的人知道使用公共无线网络时不宜做网上支付等活动。
