Check wallet backup on Trezor Safe 3

The Check backup feature is a useful way to test your wallet backup (formerly recovery seed). It is recommended to test your wallet backup before you wipe your Trezor device and before every firmware update. It allows you to double check that your wallet wackup is correct.

By starting the verification process, you are telling the device that you want to run the backup process, but you do not want the device to remember the wallet backup. Instead, the device compares the wallet backup saved in its storage and the wallet backup you have just “recovered”. If the wallet backups match, a message on your Trezor device screen will tell you that your wallet backup is okay. If they do not match, then the device screen will display an error message.
