Data Genetics researchers discovered that the three most prevalent password combinations—"1234," "1111," and "0000"—account for over 20% of all four-digit passwords. They also found that 1124 appears to be a popular choice for two-factor authentication codes.
What is unique about Data Genetics' study? They analyzed data from millions of users to come up with these results. The number one password (and the number two password) will not surprise you. The third most used password is the famous 0000 which is the default password for many websites. What might surprise you is that 1144 appears to be another popular option.
What does this mean for you? This study shows that people like to use some common passwords in their passwords, and as a result, there is a high probability that someone else using one of these passwords will encounter no trouble logging in to their account.
Here are some recommendations based on what we know about how people choose passwords: Use different words to create strong passwords. Avoid using common words or phrases. Include numbers, symbols, and non-alphabetic characters. If you add these steps to your password selection process, you will be better prepared to protect yourself against password hacks.
This four-digit code serves as your card's security code. It's important to choose unique codes for each site you log in to.
Surprisingly, over 11% of the 3.4 million passwords are 1234!!! The second most frequent 4-digit PIN in use is 1111, which accounts for more than 6% of all passwords... The Information

Despite years of security experts pushing individuals to change their passwords to more secure ones, an annual research of the most regularly used passwords showed that 123456 and 12345678 are still the most often used passwords. The study was conducted by SplashData, which analyzed the most common passwords posted on public forums and found that a lot of people choose very insecure passwords that can be easily guessed or discovered through simple data searches.
The majority of users pick extremely weak passwords that are easy to identify via brute force attacks. This means that someone could discover your password by trying every possible combination of characters until they get it right. Of course, this process is not only time-consuming but it also requires a lot of computer power, which means it is not recommended for regular users.
The best option is to use a password manager. These tools store your passwords in an encrypted form so nobody can read them except you. They also generate random passwords for you, which you can then import into your different accounts. That way, if any of your passwords are exposed in a breach, it will not lead to any further problems for other services you use.
There are many good password managers available today. Some examples are 1Password, LastPass, Dashlane. You should try out a few to see which one works best for you.
All of the apparent and easy-to-guess number combinations (12345, 111111, 123321), famous feminine names (Nicole, Jessica, Hannah), and simple sequences of letters creating a horizontal or vertical line on a QWERTY keyboard are used in the most common passwords (asdfghjkl, qazwsx, 1qaz2wsx, etc.).
Other popular passwords include words from dictionaries or thesauruses (this is why many people choose long passwords), numbers, punctuation marks, and even songs or poems. Some people write their passwords on note cards and keep them in a safe place.
The most common password of all time is "password", used by millions of people around the world. It's easy to remember and very few people write it down where it could be found by someone who shouldn't see it.
In conclusion, don't use obvious passwords, use different passwords for different sites, use strong passwords (containing upper and lowercase letters, numbers, and symbols), and only share your password with trusted individuals.
Berry examined passwords from previously leaked and exposed tables and security breaches, narrowing the results to to those with four digits [0-9]. The numbers 0-9 can be placed into 10,000 different combinations to generate a four-digit code. This means that there are 10,000 possible four-digit codes.
A typical password has eight characters, including spaces, so there are 64,000 possible passwords. However, not all of these will be suitable for everyday use. A password needs to be easy to type but difficult to guess to be considered secure. If we limit ourselves to only using letters and numbers, there are 26,000,000 possible passwords. But again, not all of these will be useful or desirable.
