What is “Check recovery seed”?

“Check recovery seed” is just a fancy name for dry-run recovery, which has been a part of the Trezor firmware since version 1.5.1. This functionality used to be available only through the command-line interface, and its integration into the Wallet interface was highly requested, which is why we added it.

It’s a simple and straightforward process. By starting the verification process, you’re telling the device that you want to run the recovery process, but that you do not want the device to remember the seed. Instead, 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, Trezor Wallet will tell you your backup is okay. If it is not the same, then the Wallet will show you an error.

Caution

Note that the dry-run is precisely the same as the normal recovery process. You should only trust the information and instructions displayed on the screen of your Trezor device. The external interface will never initialize the recovery process without your physical confirmation. The order of the words to be entered is never dictated by the interface (your browser or third-party software).

You can use the standard shuffled entry on the computer, or use the advanced recovery process if you have a Trezor One. Trezor Model T users will enter the seed words on the device’s touchscreen.

What’s 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 then set it up again. Write down the new recovery seed and then send your coins back to the newly set up Trezor.
