On Seedphrases:

Does using a passphrase lead to a higher/better entropy when creating a key? 🔑

I mean does it help if a machine tries to find your key, that won’t scan for seed phrases but for 256bit keys itself? 🤖

Or is the entropy the same on the level of the key and it is only a safety add on on the seed phrase level if someone finds the 24 words? 🤔
