How do I back up and restore Signal messages?
Applies to: Signal Messenger (Android, iOS)
Last updated: September 2025
Problem
Signal stores all messages locally on your device for privacy. If you change phones or uninstall the app, messages are lost unless you create a backup. Users often need a way to back up and restore their chats.
Solution
Signal provides encrypted local backups on Android and device transfer on iOS. Messages cannot be restored from Signal’s servers.
Step-by-step Instructions
On Android: Create a backup
- Open Signal.
- Go to Settings > Chats > Chat backups.
- Tap Turn on.
- Signal will generate a 30-digit passphrase — write it down and keep it safe.
- Tap Create backup.
- A
.backupfile will be saved in your phone’s storage.
On Android: Restore from backup
- Copy the
.backupfile to your new phone. - Install Signal and start setup.
- Tap Restore from backup.
- Enter your 30-digit passphrase.
- Your chats and media will be restored.
On iPhone: Transfer to a new device
- iOS does not allow file-based backups. Instead, Signal uses encrypted device-to-device transfer.
- Install Signal on your new iPhone.
- Keep both old and new devices nearby.
- Open Signal on both devices and follow the in-app transfer instructions.
- All messages and media will move securely.
Optional Methods or Tools
- Include Signal in your full iPhone iCloud/iTunes encrypted backup to keep a copy along with your apps.
- Store Android backup files in a secure cloud service (Google Drive, Dropbox) — but keep the passphrase private.
Best Practices / Tips
- Always enable backups if you rely on Signal daily.
- Store the 30-digit passphrase securely (e.g., password manager). Without it, backups cannot be restored.
- Periodically update backups, especially before switching devices.
- Remember: Secret and disappearing messages are also included in backups if present at the time.
