How to back up and restore a vault

How to save a password-protected backup file on each vault device, and how to import it again after you lose or replace a device.

Short answer

Back up every device separately under Settings > Vault Settings > Vault Backup. Each backup is a password-protected file. To restore a device, choose Import, then Vault, and select that file.

A vault has no recovery phrase. Each device holds its own share, and the backup file of that device is the only way to bring the share back if the device is lost, reset or replaced.

Before you start

  • Back up every device of the vault. Each file is different.
  • Choose a separate storage place for each file. The app warns: never store vault shares from different devices in the same location.
  • Choose a password for each file and keep it somewhere safe. Without the password the file cannot be opened.

Back up a device

  1. Select the vault in the wallet list.
  2. Tap Backup Vault in the reminder on the Wallet screen, or open Settings > Vault Settings > Vault Backup.
  3. Read the notice and tap Backup Vault.
  4. Enter a password in Enter your backup file password and repeat it in Verify the Vault's password.
  5. Tap Save. The iOS share sheet opens. Save the file. It carries the vault's name.
  6. The app confirms with Vault saved.
  7. Repeat these steps on every other device of the vault.
Warning

Anyone who has enough backup files and their passwords can rebuild the vault and move your funds. Never send backup files to anyone. Support will never ask for your recovery phrase, your vault backup files or their passwords.

Restore a device

Use this when you replace a device or reinstall the app. In the current version, importing a vault works in the iOS app.

  1. On a new install, tap Import wallet on the welcome screen. If you already have a wallet, open the wallet list and tap Import.
  2. On the Import Wallet screen, tap Vault.
  3. Under Vault share file, select the backup file.
  4. Enter the file's password and tap Verify password.
  5. Tap Import.

The device now holds the share from that file and can sign again together with your other devices.

If you lose a device

SituationWhat it means
Enough devices are left to signThe vault keeps working. Import the lost device's backup file on a new device to get back to full strength.
Too few devices are left, but you have the backup filesImport the backup files on new devices until enough devices can sign again.
Too few devices and too few backup filesThe vault cannot sign any more. Nobody can recover it, including THORWallet.

If a device was stolen and you think its passcode is known, move the funds to a new vault with your remaining devices.

If something goes wrong

"Invalid password"

The password does not match this file. Check for typing errors and try the passwords you used for your other devices. THORWallet cannot reset a backup password.

The Vault option is missing on the import screen

Vault import is available in the iOS app in the current version.

Two devices show the same share

If you imported one backup file on two devices, they hold the same share and cannot sign together. Import a different device's file on one of them.

Common questions

Is one backup enough for the whole vault?

No. Each device has its own share, so each device needs its own backup file. One file restores one device only.

What if I forget the backup password?

The file cannot be opened without it. THORWallet cannot reset the password. Make a new backup with a new password while the device still works.

Does an iCloud backup of my iPhone include the vault?

No. The app states that iCloud device backups do not include the vault backup file. You must save the file yourself.

I lost one device. Can I still use the vault?

Yes, as long as enough devices are left to sign. You can also import the lost device's backup file on a new device.

Can I import the same backup file on two devices?

It does not help. Both devices would hold the same share and count as one signer.
