I often hear people say 12 seed words is enough, you don’t need 24. I disagree, if someone gains access to your seed words out of order, a simple python program can run through every combination of 12 words in a matter of hours. 24 words would take nearly 2,000 years.

There are 12 factorial combinations of 12 seed words, which comes out to 479,000,000 combinations.

For 24 seed words? Over 600 TRILLION possible combinations.
