Your data available at any time with the Lissi Wallet backup

This article describes what the backup for the Lissi Wallet is and how it can be used to restore it in case of loss. Article also available in German.

What is a backup?

A backup of the Lissi Wallet saves existing credentials, contacts and their interaction history. If users no longer have access to the wallet or if they lose or replace the device, the backup enables the contents of the Lissi Wallet to be restored. Currently, the function is limited to the beta version available on testflight and Android.

The backup consists of an encrypted file containing the wallet data and a backup key. The key is used to encrypt and decrypt the data. Users need both parts (file + key) to restore the backup. The key is randomly created by the wallet and consists of 12 words.

Frequently Asked Questions (FAQ):

Can the Lissi Wallet be restored without first exporting the backup?
No, if users have not created a backup themselves before it’s not possible to restore the old data.

Does the backup include all credentials including self-scanned customer cards and PK.Pass files?
Yes, the backup includes all data that can be stored in the Lissi Wallet.

Can a backup of the Lissi Wallet be restored in another wallet?
No, it is currently not possible to restore a backup of the Lissi Wallet within a wallet of other providers. However, we are already in contact with other wallet providers and the community to enable smooth data portability.

What are the next steps?
For now, we focus on a coherent and well functioning backup process. Next, we want to enable data portability to and from other wallets. Further expansion steps include the use of hardware tokens (such as the German identity card) for additional security, as well as the possibility to store the encrypted files using a cloud backup. We will also evaluate other methods (such as social key recovery) and discuss them with the community.
