Given a passphrase dictionary attack, the passphrase would be discovered in less than a minute. Wait, what? 2,048^4 == 2^44 == 17,592,186,044,416 At 2 million hashes/second it would still take 101 [edit: actually, on average, 50] days to find this password, if it was unsalted. Perhaps if you had spent a few years of supercomputer time to generate some massive rainbow tables, you might be able to discover it quickly, but absent the need for your linkedIn password to be resistant to attacks from a nation state, you'd be pretty safe with such a password for a while. It's entirely unclear how you came to the conclusion that it could be discovered in "under a minute" with a passphrase dictionary attack.
