Imagine that I store in separate locations the 24 words and the 25th word/passphrase. If the 24 words are compromised, is there a way to brut force or guess the 25th word/passphrase? If that is impossible, you can relax when storing your 24words, knowing that they will always need the 25th word… Am I missing…
