Nowadays, proactive password checking algorithms are based on the philosophy of the dictionary attack, and they often fail to prevent some weak passwords with low entropy.

A simple example is given to exploit effective patterns to prevent low-entropy passwords as the first step of entropy-based proactive password checking.
