Antwort auf: Können geheime Passphrasen mit Gewalt erzwungen werden?
Hi! You say that you imported your Mycelium seed to Trezor. That is not a good practice, as the main role of Trezor is that it generates the private keys (represented by a seed) directly on the hardware wallet, so the keys are never exposed to an online environment.
Check this post where we explain it in more detail: [https://www.reddit.com/r/TREZOR/comments/sg8p60/import_of_a_hot_wallet_seed_to_trezor/](https://www.reddit.com/r/TREZOR/comments/sg8p60/import_of_a_hot_wallet_seed_to_trezor/).
You should create a new wallet with Trezor and transfer the funds from your Mycelium-created wallet to it.
Regarding the strength of the passphrase, please read our blog post to get an idea of what a strong passphrase looks like: https://blog.trezor.io/is-your-passphrase-strong-enough-d687f44c63af.
