Change it immediately if you are using one of the 4-digit passwords (PIN codes) listed below.
Passwords are the key to protecting your devices and applications from attackers. However, if you use easy-to-guess passwords, security will be significantly reduced.
In the digital age, protecting personal and financial information is extremely important. Passwords play a key role in keeping your devices, apps, and accounts secure. However, many people, out of fear of forgetting or convenience, use simple, easy-to-guess passwords, unintentionally creating opportunities for bad guys to attack.
Recently, a study by DataGenetics showed a list of the 10 most common and easily cracked 4-digit passwords. What's worrying is that these passwords often follow certain patterns, such as 1234 (in numerical order), repeating numbers or pairs of numbers (1111, 2222...).
The 4-digit PIN code is sometimes set simply because it is convenient and easy to remember.
In addition, many people use passwords based on their own or loved ones' birthdays, which is also a dangerous habit because this information can be easily collected.
List of 10 most popular 4-digit passwords today include:
1. 1234
2. 1111
3. 0000
4. 1212
5. 7777
6. 1004
7. 2000
8. 4444
9. 2222
10. 6969
On the contrary, the least used passwords are often more secure. According to research, the top 10 least common passwords are characterized by: not being in easy-to-guess order and not starting with the numbers 1, 2, 3, 4 or 5. For example: 8557, 8438, 9539, 7063 , 6827, 0859, 6793, 0738, 6835, 8093.
Statisticians advise that if you are using a PIN or password from both the most popular and least popular lists, you should change it because in the future, those passwords are easily captured by hacker groups.
