User manual:Creating a wallet with Shamir Backup
This article aims to provide a simple step-by-step manual for creating a new wallet utilizing the Shamir backup feature.
For detailed information about this method of securing your wallet, see Shamir Backup.
Important remarks before you start[edit]
- You will be presented with sequences of random 20 or 33 English words, each displayed on the screen of your device. These words will never be shown on your computer screen. Do not use backups offered to you by your computer.
- The word-sequences are referred to as "recovery shares". If used correctly, the recovery shares can later be used to recover a wallet in case of theft, loss, or destruction of the Trezor device.
- Keep the recovery shares written offline. Do not take pictures of your recovery shares, do not make digital copies of your recovery shares, and never upload them online.
Use paper or other more suitable platforms to keep your recovery shares offline. You can print and use the Shamir Backup Shares Sheet to make the writing process more convenient and organized.
- The recovery shares will only be presented once and then never again. It is not possible to have the device show the words ever again. Pay close attention to every word and make sure you write them down correctly and in the right order.
The process outlined in the steps below can be found illustrated and narrated in the following video:
1. Getting started[edit]
