Private Key Backup

​

Function Introduction

The MPC workspace consists of three private key shares. Two of these shares are encrypted and stored with Microsoft Cloud Services and Amazon Cloud Services, while the other is kept on your local device. To ensure the security of your assets, it is vital to promptly backup the locally stored private key share and keep it safe. These private key shares exist in the form of a recovery phrase, making them easy to remember.

There are two backup options for private key shares: local backup and cloud backup.
