4 Ways to Set a Perfect Password
You will need your ID and password to use web services such as watching movies and checking your bank account over the Internet. However, once the password is leaked or analyzed, there is a risk that personal information will be spread all over the world. PC World, an IT news site, lists four things to keep in mind to make your passwords more secure.
How to pick the perfect password | PCWorld
◆ 1: Make the password as long as possible
The most used password in 2020 was '123456', announced by NordPass , the developer of password managers. There are many other passwords in the ranking, but they are all very simple and short and can be cracked in an instant.

Passwords can be easily cracked by guessing hundreds of millions of patterns of passwords per second using the computing power of a PC, but the more characters there are, the more difficult it is to crack. The table below shows the average time it takes to crack a password, published by Terahash, a security company that undertakes password cracking. If the number of characters in the password exceeds 10 characters (letter 10), it will take at least 3 days to analyze, so it can be said that it is highly secure.
However, you should avoid things that are easy to predict, such as the date of your birthday or your name. Since the attacker has registered a character string that is often used and a known password, even if the number of characters is large, it can be analyzed in an instant.
Also, password cracking tools basically try to guess in lowercase letters, so the risk of cracking is greatly reduced by simply combining special characters such as lowercase letters, uppercase letters, numbers, and%.
In addition, PCWorld introduces the following techniques as strategies for creating more secure passwords.
・ Use a series of words that have a big meaning for you, such as your favorite sayings and lines, and your favorite taste of ice cream.
・ Combine words in foreign languages.
・ Combine poetry and Old English.
-Mix the titles of the books on the bookshelf to make a word.
・ Do not mix information that is open on SNS such as Facebook and Twitter.
◆ 2: Create a unique password for each site or service
If one password is reused, if one service leaks the ID and password, the other service may be compromised. Therefore, it is necessary to keep in mind 'one password for one service'.
◆ 3: Manage passwords instead of remembering them
The more passwords you have, the harder it is to remember, but major web browsers such as Chrome, Firefox, Safari, and Edge have a 'save password and autofill feature'. Therefore, you do not have to remember the password you set.
Also, password managers such as LastPass , Bitwarden , and Passit are more secure than storing passwords in your browser. Password manager is a tool that can encrypt and save IDs and passwords. Some password managers work with your PC and smartphone, so you only need to remember one master password to manage multiple passwords across devices at once.
◆ 4: Be aware that there is no perfect password forever
No matter how strong your password is, it doesn't make sense if it's cracked. If you suspect that your password has been leaked, you should change it as soon as possible.
There is also a site where you can check whether personal information has been leaked from the email address or user name used to log in to the service, so use this to check if your ID and password have been leaked. Checking is also one way.
You can find out if you were hacked and included in the past leak list by searching by your e-mail address or ID name 'Have I been pwned?' --GIGAZINE
Finally, PCWorld says, 'Passwords are becoming less important. We are already living in an era of logging in to PCs and banks with multi-factor authentication, which authenticates a combination of multiple factors such as faces, fingerprints, and phones. , These options aren't universal yet. As long as the password remains, it's important to make it harder to crack. '
