Signal adds encypted local backup support to iOS, desktop apps
Signal 8.30 completes its end-to-end encrypted backup rollout, bringing on-device backups to iOS and desktop with a unified cross-platform format.
Signal version 8.30 extends on-device encrypted backups to iOS, Linux, macOS, and Windows, completing a feature first shipped on Android nearly a year ago. Hosted backups are limited to 45 days of media and 128 KB per message for free users (100 GB paid), while local backups have no size restrictions; both require a recovery key, with hosted keys also rotating daily in a Trusted Execution Environment. The update adds direct iPhone-to-iPhone transfer over an encrypted Wi-Fi Aware link, and Signal notes threat actors have already begun targeting backup recovery keys.
