Brute Force Attempts to Guess a 12-Phrase Combination

Assuming that each phrase contains 4 words, and each word is chosen from a list of 10,000 commonly used words, the total number of possible combinations is:

10,000^4 * 12 = 1.2 x 10^21

Therefore, it would take an average of 5.9 x 10^20 brute force attempts to guess a 12-phrase combination. However, with the use of password cracking software and techniques, this number could potentially be reduced. It is important to use strong and unique passwords to protect personal information and accounts.
