Now you can securely link multiple phones to one Signal account

现在，你可以将多部手机安全地关联至同一个 Signal 账号

Signal’s secure messenger can easily work across multiple Android devices and iPhones now. Signal 安全通讯软件现在可以轻松地在多台 Android 设备和 iPhone 之间协同工作。

You can link more devices with one phone number on Signal now, including an Android phone or iPhone. Signal already supported linking PCs and iPads, but not additional phones. 现在，你可以在 Signal 上使用同一个手机号码关联更多设备，包括 Android 手机或 iPhone。此前，Signal 已经支持关联电脑和 iPad，但并不支持关联额外的手机。

When you link a device on Signal, you can check and respond to new messages across all of your linked devices. You can also choose whether or not to transfer an end-to-end encrypted copy of your previous messages to each newly linked device to mitigate the risk of devices that might be shared, lost, or compromised. 当你在 Signal 上关联设备后，你可以在所有已关联的设备上查看并回复新消息。你还可以选择是否将之前消息的端到端加密副本传输到每台新关联的设备上，以降低设备被共享、丢失或遭到入侵所带来的风险。

The update is rolling out now with Signal version 8.20 on Android and version 8.22 for iPhone / iPad. 此次更新现已推出，Android 版本为 8.20，iPhone/iPad 版本为 8.22。

Signal also says it has made “significant interface improvements to better support large devices,” including several improvements for foldable phones, which helped enable support for Android tablets. However, Signal says the large-screen version of its Android app is “still a work in progress,” and that it’s working on optimizing the interface for its Chromebook app, as well. Signal 还表示，他们对界面进行了“重大改进，以更好地支持大屏设备”，包括针对折叠屏手机的多项优化，这也促成了对 Android 平板电脑的支持。不过，Signal 表示其 Android 应用的大屏版本“仍在开发中”，目前也正在优化 Chromebook 应用的界面。
