Anyone have details about how Messages in iCloud works? Is it end-to-end encrypted?
- Store your messages, photos, and other attachments in iCloud and free up space on your devices
- All your messages appear when you sign into a new device with the same iMessage account
- When you delete messages and conversations they are instantly removed from all your devices
- Your conversations continue to be end-to-end encrypted
This Messages in iCloud support article has more details on how to set it up: https://support.apple.com/en-us/HT208532
Now that a new device can receive older messages, and assuming apple doesn't have the keys to your messages, who does the sending? Does one of your existing devices have to relay all the messages by downloading, decrypting, and re-encrypting for the target?
> CloudKit end-to-end encryption
> Apple Pay Cash, User keywords, Siri Intelligence, and Hey Siri use CloudKit end-to-end encryption with a CloudKit service key protected by iCloud Keychain syncing. For these CloudKit containers, the key hierarchy is rooted in iCloud Keychain and therefore shares the security characteristics of iCloud Keychain—the keys are available only on the user’s trusted devices, and not to Apple or any third party. If access to iCloud Keychain data is lost (see “Escrow security” section later in paper), the data in CloudKit is reset, and if data is available from the trusted local device it is re-uploaded to CloudKit.
I have four threads with my wife, and each update it seems a random one becomes active because of the From address being reset.
This has been an issue since, like, forever.
Worth checking the "new messages from" setting on all of your devices (on both sides probably)
I agree though there is a shortcoming here.
• Does "Messages in iCloud" work for syncing regular SMS messages too, or does it only include iMessages?
• It looks like there's no corresponding macOS update today to add Messages in iCloud support, is there? Should we expect it to be bundled into the next minor macOS patch, or is it more likely to be pushed into macOS 10.14?
It works for all messages, that is, SMS and iMessages. You turn it on in the iCloud account settings and it uploads everything. The device needs to be connected to mains power though. Otherwise it pauses the sync process until you do. The upload/download progress is shown at the bottom of the screen in the Messages app.

I'd also suggest sending feedback to Apple periodically at https://www.apple.com/feedback even if it seems like the feedback is never taken into account for changes or new features.
