iPhone，iPad或Mac上的“丢失模式”是什么？

If you ever lose your iPhone, iPad, Mac, or Apple Watch, you should put it in “Lost Mode.” Lost Mode locks your device to protect your personal information, tracks its location, and places a customizable message on its lock screen.

如果您丢失了iPhone，iPad，Mac或Apple Watch，则应将其置于“丢失模式”。 丢失模式会锁定您的设备，以保护您的个人信息，跟踪其位置并在其锁定屏幕上显示可自定义的消息。

什么时候应该使用丢失模式？ (When Should You Use Lost Mode?)

Apple’s Find My iPhone and Find My Mac tools let you remotely track and erase your devices. You can even play a sound on them—which will help if you drop your phone in your home’s couch cushions, for example.

Apple的“ 查找我的iPhone”和“查找我的Mac”工具可让您远程跟踪和擦除设备。 您甚至可以在它们上播放声音-例如，如果将手机放在家里的沙发垫上，这将有所帮助。

For iPhones and iPads, the battery will even last a bit longer, giving you precious time to find your device before the battery dies.

对于iPhone和iPad，电池甚至可以使用更长的时间，使您有宝贵的时间在电池耗尽之前找到设备。

This means that a thief shouldn’t be able to get access to your data without your passcode or password. However, Lost Mode prevents the thief from using the device and seeing personal data that would normally be visible, like notifications on your lock screen.

iPhone和iPad具有加密的存储，甚至Apple的Mac现在都默认启用FileVault加密 。 这意味着如果没有密码或密码，小偷就无法访问您的数据。 但是，“丢失模式”可防止小偷使用设备并查看通常可见的个人数据，例如锁定屏幕上的通知。

丢失模式有什么作用？ (What Does Lost Mode Do?)

Here’s what happens in Lost Mode. First, if your iPhone or iPad has a passcode or PIN, that passcode will be required to unlock it—Touch ID and Face ID won’t work. If you haven’t set a passcode, you’ll be prompted to set one immediately. If you’re putting a Mac in Lost Mode, you’ll be prompted t
