Signal Introduces Encrypted Message Backups for iPhone
Signal has launched its long-awaited secure message backup feature for iOS, giving iPhone users the ability to preserve encrypted chats when switching devices or reinstalling the app. Previously exclusive to Android, this update extends end-to-end encrypted (E2EE) backups to Apple’s ecosystem, cementing Signal’s status as the most private messaging app available.
Why Signal’s iOS Backup Feature Is a Privacy Milestone
Signal’s core promise is “no compromises” on privacy—messages are readable only by the sender and recipient. But until now, iOS users risked losing entire chat histories without a backup option. This update fixes that gap, offering:
- True end-to-end encryption: Backups are locked with a user-controlled key.
- iCloud or local storage: Encrypted files stay unreadable even on Apple’s servers.
- No backdoor access: Not even Signal can decrypt your backups.
The feature is critical for journalists, activists, and businesses relying on secure communication.
How to Set Up Encrypted Backups on Signal (iOS)
- Go to Settings > Chats > Chat Backups.
- Toggle Enable Backups and pick iCloud or Local Storage.
- Securely save your 30-digit recovery phrase—losing it means losing access.
Signal vs. WhatsApp & iMessage: Privacy Compared
| Feature | Signal (iOS) | WhatsApp | iMessage |
|——————|——————–|——————–|——————–|
| Backup Encryption | E2EE (user key) | Unencrypted (default) | Encrypted (Apple holds keys) |
| Cloud Storage Risk | Zero (user-controlled) | High (Google/iCloud) | Moderate (Apple can access) |
Signal’s model ensures only you hold the decryption keys—unlike competitors vulnerable to subpoenas or breaches.
Challenges and Considerations
- Recovery phrase = sole access: No reset option exists.
- iCloud dependency: While encrypted, backups could still be deleted if your account is compromised.
What Experts and Users Are Saying
Privacy advocates applaud the move:
“Signal keeps raising the bar. This eliminates a major iOS weak spot.”
— Apar Gupta, Internet Freedom Foundation
Users on Reddit and Twitter highlight relief over no more lost chats during device upgrades.
The Bottom Line
With encrypted backups now on iOS, Signal reinforces its lead in private messaging. Enable this feature to protect years of conversations—without sacrificing security.
