I have made the password quite challenging, but at the same time it is possible to commit it to memory.
Password is not the same thing as Passphrase.
You can have multiple passphrases and they are all acting as salt to your seed words and creating separate accounts.
Hiding this account is possible with settings option in Trezor Suite app, but if you forget passprhase you will lose your coins even if you have seed phrase words.
Because as I understand, I have one seedphrase for the two wallets (hidden, standard).
Seedphrase is one, ontop of that you can create multiple accounts with different passphrases.
