The passphrase is like a 25th word of the seed. Every passphrase gives you a different wallet, and if you forget the passphrase (or lose the seed) the BTC stored in the wallet are lost.

So johoe, Where do I put the passphrase when recovering? It's much longer than the BIP44 words, so It cannot be in the seed.

You do not use the passphrase when recovering only when accessing the wallet. You can also recover the Trezor seed to Mycelium wallet on Android.

Thanks for prompt reply, Cereberus.

I tried that guide before posting (a bit old, different software version now), but It doesn't work with passphrases. I couldn't find the option to put the passphrase, and of course, It doesn't rebuild the wallet. Does anyone succeeded in recovering Trezor with passphrase using Electrum/Mycelium?

Moreover, you cannot bypass the passphrase, as you can read in their FAQ (https://doc.satoshilabs.com/trezor-user/advanced_settings.html#multi-passphrase-encryption-hidden-wallets)

The flip side to this extreme level of security is that if you forget your passphrase your bitcoins are lost. Really lost!

b) when using hidden wallets, how is the passphrase generated within the device when multiple wallets are used? Is the seed related in this process? Because if I use the seed to recover my wallets, the passphrase couldn't be generated unless you put it explicitly, so it'll be impossible to access my wallets If I only know the seed, therefore all my BTC will be lost, aren't they?

Hi people!!

I recently purchased a Trezor to use it as a secure vault for my small BTC, and it's an amazing device: very high secure, U2F compliance, some good apps for everyday usage (also thinking about buying another one (new model?) for backup purposes, but I have 2 questions I cannot answer. Perhaps they're answered in another posts, but I couldn't find them (sorry if that's so):

a) what may happen if the domain mytrezor.com is down because SatoshiLabs crashes? I couldn't have access to the device to use my private keys to make online transactions. Is there any option to download source code and create a webserver using localhost and a specific /etc/hosts entry?

b) when using hidden wallets, how is the passphrase generated within the device when multiple wallets are used? Is the seed related in this process? Because if I use the seed to recover my wallets, the passphrase couldn't be generated unless you put it explicitly, so it'll be impossible to access my wallets If I only know the seed, therefore all my BTC will be lost, aren't they?

Thanks for your help ;-)

I am answering the a question here. You can use trezor with electrum. It means their seed is compatible. Just restore a wallet with your trezor seed to the electrum wallet and then think what you can do.

But also why not try to ask the question 2. If you have the seed you can bypass the passphrase and set a new one when you restore your wallet through the seed.
