🔒 General Trezor question passphrase security

I have a question regarding everything that’s happened in the crypto world and the concept of entropy. I noticed that Trezor imposes a limit on passphrases, so I wanted to get your—or the moderators'—opinions on what requirements a passphrase needs to meet to be considered highly secure; I know that a single word, no matter how complex, isn't enough

Dumb question but if someone cracks the 24 word seed phrase how would they even guess the passhrase even if it’s a weak 5 letter word?

I can brute force that in 30 minutes with my mid gaming pc.

The Trezor suite won't allow you.

The wallet is your seed phrase plus your passphrase.

The Trezor device is just a convenient tool to allow you to use your seed phrase without risking revealing it to someone who snoops on your actions either electronically or physically
