Users need an "identity" to use imToken, but an identity can only be recovered by the Mnemonic. So, users who only backed up the private key/Keystore will need to "create identity" and then import the private key / Keystore recovery wallet.
Import private key / Keystore:
- Create an identity and enter imToken
- Click "My Profile" in the lower right corner
- Click "Manage your wallet" - "Add wallet"
- Select the wallet type
- Click "Import" to import the private key / Keystore
- Wallet recovery success
Note: The corresponding password is required when importing Keystore.
