Hi all,
I have released a JavaScript-based Trezor/BIP39 recovery tool at
http://anaoum.github.io/trezor-recovery/This allows you to regenerate all the private/public keys used by your Trezor given the mnemonic and passphrase. This would be handy if, for example, your Trezor was stolen and you did not have another Trezor available to restore your mnemonic to.
You can run it completely offline from a live distro if you'd like. This can also be handy if you want to verify that you have correctly backed up your mnemonic/passphrase.
Source is open and available at
https://github.com/anaoum/trezor-recoveryI originally forked the code at
https://github.com/bip32/bip32.github.ioLet me know if you have any questions!
Thanks,
Andrew.
