[Unauthorized] Microsoft plans to set a password

Today, I was unaware of seeing a password security check on Microsoft's website, so I tried my own nice password and the result showed weak. I did not expect that the passwords I used for many years are not secure. I have learned a lot from Microsoft's explanation of the security passwords. I 'd like to share it with you ~

Step 6 create a secure password

For attackers, a secure password is like a random string, but it is hard to remember a random string.

Using a sentence that is easy to remember for you as the basis to create a random string is difficult to guess than other people.

1. Select a sentence that is easy to remember

For example, "My son Aiden is three years old ."

2. Convert the sentence into a password.

A string consisting of the first letter of each word in a sentence, for example, "msaityo ".

3. add complexity for the password

Mix uppercase and lowercase letters and numbers in the password. You can also use a deliberate spelling mistake to increase the complexity of the password.
For example, in the preceding example, you can use the number "3" to replace the word "three", and then change the password to "msai3yo ".

4. Replace special characters

Replace some letter-like characters or numbers with some of the letters in the password to make the password more complex.
The password above this policy will be changed to "M $8ni3y0 ".

5. Use password Checker to check the password strength

Password Checker can evaluate the password strength online.

6. Password protection

Use the password as confidential information for careful protection. For details, refer to 5 tips to help keep your passwords secret.

Feature length of secure passwords

* Each character added to the password improves the security of the password.
* The password must contain more than 8 characters, and the password must contain more than 14 characters.

Complexity

* The more characters in the password, the more difficult it is to guess.
* The combination of length and different symbols is the ideal password setting method.
* Use the entire keyboard to set the password. Do not use letters or numbers separately.

Easy to remember and difficult to guess

* The simplest way to remember a password is to write it down (a good brain is better than a bad pen ).
* You can write down a password, but you must ensure its security.

Password settings

To avoid low password security, pay attention to the following points:

* Avoid consecutive or repeated characters
"12345678", "222222", "abcdefg", or adjacent characters on the keyboard.

* Avoid replacing numbers or symbols that appear to be "similar"
For example, replace "I" in "m1cr0 $ 0ft" with "1" or "A" in "P @ ssw0rd" with "@".
This replacement is more effective in combination with other methods, such as length and misspelling.

* Avoid using login names
Do not use personal names, birthdays, social security numbers, or similar lover information.
Such information is the first content to be tested by attackers, and is easily obtained from the Internet, online resumes, or other shared resources.

* Avoid dictionary in any language
Attackers can use cracking tools that contain many types of dictionary libraries to quickly guess passwords, including spelling, common spelling errors, foul words, and some replacement methods.

* Avoid using the same password for all accounts
If the password is used on a computer or online system, consider whether other information protected by the password is also affected.
It is critical to use different passwords in different systems.

* Pay attention to password recovery questions
Many websites provide a "password" service, which allows you to set some confidential questions. When you forget the password, you can get the password by answering the confidential questions.
These confidential questions are generally given randomly, but the answers are often obtained randomly on the Internet. Therefore, be cautious when selecting confidential questions.

* Avoid using online storage
If attackers find that your password is stored on the Internet or on a computer, they will soon obtain all your information.
