Security companyNordPassAccording to the report, the most used password in 2021 in Japan was still easy, but it was different from the most used password in the world.
A survey is also being conducted on the average number of password leaks per capita in countries around the world.
“123456” was used more than 100 million times
NordPassWas heavily used in 2021 in collaboration with an independent researcher specializing in cybersecurity incident investigations.passwordI investigated.
We are conducting surveys in 50 countries around the world, and the database is said to have reached 4 terabytes.
Result of investigation,The most used password in the world in 2021 was “123456”, which was used more than 100 million times in total.It’s called.
The 2nd place “123456789” and the 3rd place “12345” were probably used when the number of digits required for the password was different.
Including “qwerty” in 3rd place and “password” in 5th placeThe most commonly used high-level passwords are very weak passwords that can be cracked in less than a second.It is said that.
Trends in commonly used passwords by gender have also been investigated, for example, more than 220,000 women use “ilove you” as their password, compared to less than 100,000 men.
“Password” is popular in Japan

- A mixture of alphabets and numbers
- Must be a string of appropriate length
- Do not arrange them in an easy-to-understand manner or combine them easily.

Even though it’s averageCalculation that if there are two people, at least one of them is leaking the passwordHowever, it cannot be said that it is safe.
