Signal Secure Backups: how to set them up and where to store the recovery key
Signal used to have one hard rule: your messages lived on your device and nowhere else. Lose the phone, lose the history. That changed. Signal Secure Backups are now live on Android and iOS. They are end-to-end encrypted, opt-in, and Signal cannot read them. If your Signal threads touch treasury approvals, deployment coordination or incident response, this is worth ten minutes of your attention. Setup takes five.
