Why does it generate six words?

What we are really calculating is a checksum made up of the last 4 bits of information in the private key. Since each word is 7 bits this means there are 3 bits remaining. 3 bits of information is missing

Why is this secure?

There are 2048^24 = 2.9642775e+79 possible combinations

If 8 Billion people each made one million guesses per second it would take over 1.0e+56 years to brute force every combination
