Weak passwords are the leading cause of data breaches and account hacks. Many users unknowingly use passwords that can be cracked in seconds by modern hacking tools. Our Password Strength Checker analyzes your password against advanced metrics like entropy and crack time, and even checks if it has appeared in known data leaks. By ensuring your passwords are mathematically strong and uncompromised, you significantly reduce the risk of identity theft and unauthorized access to your accounts.
