Secure password management
Create a strong password
In order to manage your passwords safely, you first need to create a complex password that is difficult for others to guess.
Creating a complex and strong password like the one below will make it harder for unauthorized logins.
・ Increase password length
The more characters, the longer it will take to crack the password.
At least 12 characters, more is more robust.
Advances in technology have also improved the speed at which passwords can be cracked, meaning that simple passwords with a small number of digits can be cracked in a short amount of time.
・ A mix of uppercase and lowercase letters, numbers, and symbols
As the number of types of characters used increases, the number of combinations of patterns increases rapidly.
For example, if there are only 26 letters of the alphabet, there are about 300 million ways with 6 digits.However, in the case of 94 types of uppercase letters, lowercase letters, numbers, and symbols, there are about 690 billion ways.
If you are attacked by Brute force attack, which uses brute force to enter a password pattern, increasing the number of digits and character types will make it more secure as it will take more time to analyze.
・ Don't use meaningful words
Using dates such as first and last names and dates of birth makes it easier to guess.
Using a place name or a word found in a dictionary can also make your password easier to crack.
Dictionary attacks attempt to log in by combining words, names, etc. registered in the dictionary, so if you use those characters, there is a possibility that they will be deciphered in a short time.
・ Do not use simple sequences of characters
Sequences such as 12345, 00000, and abcde, as well as numbers and words that are simply rearranged in reverse order, are easier to guess.
Character strings commonly used in passwords, such as simple sequences of letters and numbers, can be easily cracked using brute force.
How to store your password
In addition to creating a secure password, how you store your password is also important.
You need to make sure that no one else knows about it, and that you don't forget it yourself.
・ Write on paper
The advantage of managing information by filling it out on paper is that it is easy to manage and there is no need to worry about it being leaked over the internet.
Additionally, data will not be lost due to malfunctions or malfunctions.
However, you must be careful not to lose or steal the completed form.
In an office, etc., you must keep it out of sight of others and store it in a safe manner, such as on a locked desk.
・ Manage with files
Managing passwords in files such as Word, Excel, or Notepad has the advantage of being easy to enter and update.
However, if you are connected to the Internet, there is a risk that your data may be leaked or lost due to malfunctions or malfunctions.
Therefore, it is necessary to password protect the file itself and take regular backups.
・ Use password management tools
Managing passwords with a password management tool has the advantage of making it easier to create and manage passwords.
You can automatically create complex passwords and automatically enter passwords when logging in, saving you the trouble of entering them.
However, if the security of the management tool itself is weak, passwords may be leaked or lost.
Paid tools also have disadvantages such as high costs and sudden termination of the service, making it unusable.
Don't reuse passwords
Regarding how to use passwords, it is important not to reuse them for multiple services.
If your account information is leaked from any service, there is a high possibility that unauthorized logins will occur on other services.
Creating and managing separate passwords for each service is difficult, but the core password method is a way to create passwords that are complex and easy to remember.
This is done by creating one complex core password and adding different strings for each service.
With this method, you only need to remember the core password and each rule to manage it.
About changing your password regularly
In the past, passwords were said to need to be changed regularly, but now they are no longer required to be changed regularly.
Changing your passwords regularly can make your passwords simpler or more likely to be used repeatedly, which can actually make your passwords more dangerous.
