In plain words
Think of your message history like a box of letters you want to keep private. Just like you would want to take this box with you if you moved houses, Signal now lets you take your message history with you when you switch devices, like from an Android phone to an iPhone, and it stays encrypted, like the box is locked and only you have the key¹.
How it actually works
This new feature is part of Signal's updates to its backup system, which includes encrypted local backups and the ability to restore these backups on different platforms like Android, iOS, Linux, macOS, and Windows. This means you can switch between these devices and still access your message history.
