If your passphrase is even remotely human-generated, the dictionary will crack it. : The generator runs this phrase through a hashing algorithm

In 2015, security researcher Ryan Castellucci launched a project called "Brainflayer." He scanned the entire Bitcoin blockchain for addresses that matched common brain wallet passphrases. He found millions of dollars. Within hours of a naive user funding a brain wallet, his bots would sweep the funds. He found millions of dollars

Because human-generated passphrases lack entropy (randomness), attackers can use massive "dictionaries" or wordlists to guess them.

If you Google "bitcoin brain wallet generator," you will find dozens of websites. Using them is akin to shouting your bank password in a crowded stadium.
