Differences between strong and weak passwords

Why are passwords so weak and strong? What are the criteria for assessing the strength of a password? Are lengths, numbers or special characters? Join us to learn and learn how to create a perfect password protection account offline.

The difference between strong and weak passwords

Strong passwords contain random characters and weak passwords are easy to predict

Generate passwords from as many random characters as possible. Why so? Because if a password is created using a numeric or keyboard, it is easy for hackers to guess it using a dictionary-based password-breaking tool.

Strong passwords are always complex, weak passwords are often simple

If you only use numbers in a password, it can be broken in just a few seconds with a dedicated tool. Generating passwords in numeric form increases the possibilities of matching. In the meantime, bad guys will spend more time and effort to crack passwords. Therefore, remember to add special characters to the password to protect the account.

Good passwords are always long, weak passwords are short

The length of the password is one of the most important factors determining whether it is "hacked" quickly or slowly. The longer the password, the better.

In theory, password-cracking tools require a lot of time and computing power to decode long passwords (for example, 15 characters or more). However, advances in future technology may change the limits of modern password standards. Therefore, it is best to still set a password as long as possible.

How to set a password should be avoided

Reuse the old password

Reusing old passwords seems to save time and not have to think much, but, it increases the risk of the account being "hacked" because if someone accidentally knows the old password, and then use them Your personal information is very likely to be stolen.

In order of the keyboard

Setting a password according to the keyboard can help you bypass the system's password complexity check. However, this form is very often used by hackers to crack passwords. Even the long and relatively complex keyboard model may have been in the hack tool's dictionary file.

Duplicate password

Simply typing twice the password is enough to meet the length requirements. However, it does not make this protective layer stronger. In fact, it's very weak because you've used a password generation template that almost everyone thinks of first.

Some word in a dictionary

Again, don't use whole meaningful words in passwords because hacking tools are designed to target passwords that contain whole words or partial words.

Note for system administrators

Administrators absolutely should not allow users to create weak passwords if you want to ensure the rights of users and the safety of the system. They need to ensure that the workstations and servers under management have a checking policy that forces users to set strong passwords when creating accounts.

A lot of people think their passwords are safe because of the notion that a hacker can only make three password attempts before an account is locked. But we don't know that hackers first steal the password file, and then try to "crack" the file while offline. They will only log in online to the system after having the correct password on hand. Therefore, do not be subjective. Hope the above tips will help you create a perfect password to protect your online account.
