Signal Bolsters Message Safety with New Secure Backup Feature

Signal users can now protect their chat history through a new secure backup system, available in the Android beta and set for wider release. The platform’s secure backup enables daily, end-to-end encrypted snapshots of text messages and media, complemented by both free and paid storage tiers. Central to the system’s security is a device-generated, 64-character recovery key—the only way to unlock the backup—which Signal cannot recover if lost.
