Test your seed backup: Dry-run recovery

So you have made a backup of your device and wrote down your unique 12- or 24-word recovery seed. Good job, don’t forget to keep it secure! But something in the back of your mind bothers you, and you cannot quit thinking that maybe you have made a mistake. Is it better to start over again to be sure? Or should you take the risk and send your savings to your TREZOR?

Starting today, you can rest easy, without necessarily needing to wipe and launch the setup process all over again. In the TREZOR Wallet user interface, just go to device settings by clicking on your device name, and then select Advanced > Check recovery seed. Follow the instructions and, in the end, the device will tell you the status of your recovery seed. Then, you can be confident that your seed is correct, or you will know for sure you need to generate a new one.

Pro tip for TREZOR One users: Use the Advanced Recovery option. Now is an excellent time to try the new method of device recovery without any worries. The Advanced Recovery does not reveal any of your seed words to the computer, making it safer to use. More about Advanced Recovery…

What is “Check recovery seed”?

Check recovery seed” is just a fancy name for recovery dry-run, which has been a part of TREZOR firmware since version 1.5.1. This functionality has been available only through the command line interface, and its integration to the Wallet interface was often requested. That is why we decided to add it.

It is, in fact, quite a simple and straightforward process. By starting the verification process, you are telling the device that you want to run the recovery process, but you do not want the device to remember the seed. Instead, in the end, the device compares the seed saved in its storage and the seed you have just “recovered,” and the result of this comparison is sent to the Wallet interface. If the seeds match, the TREZOR Wallet will tell you your backup is okay. If it is not the same, then the Wallet will show you an error.

The warnings shown on the device during this process are related to a full recovery. If you are running dry-run, you can ignore the warnings related to the recovery process.

Note that the dry-run is precisely the same as the normal recovery process. You can use the standard shuffled entry on the computer, or use the advanced recovery. TREZOR Model T users will enter the seed words on the device display.

What is next?

If the Wallet interface tells you your seed matches, then you can rest easy, knowing you have your backup.

If the Wallet displays an error, we strongly recommend moving all your coins to a new wallet, with a new seed. Move your coins to a different wallet first, wipe your device and set it up again. Write down the new recovery seed and then send your coins back to the newly initialized TREZOR.
