Hackers use what's called a brute-force technique, which can take anywhere from seconds to years to guess your password depending on the complexity. It's often a computer program that keeps stuffing words until it hits the jackpot. All hackers need for it to work is to upload a database with popular passwords, words from a dictionary, or passwords leaked in the past. Therefore, the more complex the password is, the less of the chance they have to break it. And the less you reuse passwords, the safer you'll be from potential database breaches.
Humans aren't very good at coming up with passwords that are either of those things, let alone both. 81% of data breaches are caused by reused or weak passwords, so random, unique passwords are your best defense against online threats. Follow the rules set above and you'll be on the right track.
Inadequate password security could not only endanger the cyber safety of individuals and customers, but also could lead to financial troubles. Cybercriminals are often looking for ways to access personal banking information or use ransomware to make themselves a profit. Businesses and individuals within the U.S. lost nearly $4.2 billion to cybercrimes within the last year alone.
