While this feature is not found in device settings, Trezor Model T users can use Shamir backup to protect their recovery seed from loss or damage.
Shamir backup creates multiple shares instead of a single seed. Users can set a threshold of shares required to recover their wallet. The extra shares are a backup in case some of the others are lost, stolen or damaged.
To create a Shamir backup on a used Trezor Model T, the memory must be wiped. Make sure you have your recovery seed safely backed up for any wallet already loaded on the device.
- With a new or wiped Trezor Model T, follow the Onboarding to create a Shamir share backup; alternatively, visit ⚙️ Settings > Device and choose Create backup.
- Set a total number of shares.
- Set a threshold for recovery.
- Write down all words of each share in order, using a separate piece of paper for each share.
- Once complete, secure each share in a safe location isolated from the others.
- To recover your funds, you will need to collect as many shares as the threshold you set.
