Your key share is stored locally on your device. If the device is lost, stolen, or reset, you lose the ability to sign transactions — so back up your key share immediately after creating your wallet.
Backup options
The Cobo Agentic Wallet app offers two backup methods:
| Method | How it works | Best for |
|---|
| Cloud backup | Encrypts your key share and stores it in your cloud account (Google Drive or iCloud) | Convenience — easy to restore on a new device |
| Local backup | Exports your encrypted key share as a file you store yourself | Full control — no dependency on a cloud provider |
Cobo recommends completing both. Cloud backup is convenient but depends on your cloud account security. Local backup is fully under your control but requires you to manage the file.
During backup, you will be asked to set a recovery passphrase. You must enter this password whenever you restore your key share. If you forget the password or lose the backup file, your key share is permanently unrecoverable.
Restore from backup
If you lose your phone or uninstall the app, you lose access to your key share. To get it back, install the Cobo Agentic Wallet app on your new device, sign in to your account, and import your key share from cloud or local backup.
