Crack how? With 4-5 words you're going to have a pretty long password so bruteforce is out. Do you mean that if you will have one of my password you will have the rest? That's because I gave you obvious example as a joke. What if my password is TakePicturesOfYou. What other password are possible? How will you crack them?
Take the lyrics of the top 1000 popular english songs, and do a rolling hash of 5 words at a time. To account for capitalization, you would have to multiplely the dataset a few times but I bet you most passwords created in this manner would be easily cracked using this method.
That's not easy. I mean it's not that hard computationally but you're talking about very specific attack requiring some dedicated tools. Real life you would have two scenarios:
This would be bad pretty much only in the very specific scenario of hackers trying to hack my specific account and having leaked hashes of password for this account.
Still I wouldn't really use this method. I'm just saying it's better method than some printed card generating short alphanumeric password.
Fair. I guess I'm just being nitpicky.
Crackers use words and phases, they don't just start at 00000000 and head for zzzzzzzz. It's easier to crack a 16 char phrase of mangled words than 16 random chars.
