Set a secure password for ten iron laws (1)

During the process of using the computer, we are dealing with passwords all the time. If the password you set is guessed or deciphered by others, then important information and personal privacy will be revealed. So how to set a secure password is a big deal related to each. Below we will introduce you to the ten military regulations that must be observed in the process of setting up the password.
First, as long as possible

In general, the password is required to be no less than 6 digits. It can be seen that passwords of less than 6 digits are extremely cracked. From the point of view of password cracking, the most common method is brute force cracking. One of the most typical features of brute force cracking is to mathematically arrange the characters that may be used, and experiment one by one until the correct password is found. If we increase the number of digits, friends who know the combination of the mathematics rankings www.it8g.com will know how many permutations will be generated for each additional digit. Therefore, the password is as long as possible is the first military regulation we must first observe. Even more than 6 characters using repeated characters increase the difficulty of deciphering.

Second, as strange as possible

There are many users who like to use their own name, nickname, date of birth, phone number or some other frequently used words as the content of the password. Everyone knows that contradictions are often generated internally. Within the company, this information is often well known. This way, when you enter the password, others can guess the contents of the password with a little attention. Therefore, if you are worried that the password you set is not easy to remember, you can add some characters that you know before and after the password to create confusion.

Third, as complex as possible

Simple numbers, letters, and even repeated use of a character, so although the number of passwords is relatively long, it seems difficult to be cracked. In fact, simple numbers and characters are easily deciphered. Therefore, we need to include letters, numbers, and various symbols when setting the password. If it is case sensitive, then the case should be used alternately, so that the passwords formed will be much safer.

Fourth, from the back to the front of the order

When setting a password, the common habits of people start from a smaller order a, b, c, d or 1, 2, 3, This just satisfies the cracking order of brute force, because they are calculated according to the natural ordering of letters and numbers. Therefore, if we set the first digit of the password to be followed by z, the probability of cracking will be much less.

V. Easy to forget password

Both passwords are long enough and complex enough to prevent hackers, but they also bring a lot of input to their own trouble. If the time is long, it is easy to forget and it is inconvenient to use. In fact, you don't have to worry about this. You can use the familiar content when setting the settings, and then add a certain character to the front and the end of the password you set. Www.it8g.com can also use a lot of familiar content to superimpose, such as your own nickname plus the phone number and the last three digits of the mobile number, and then the name of the primary school you attended and the last letter of the name, etc. It is familiar to oneself, there are no forgotten concerns, and it also serves the purpose of paralyzing others.

Six, do not use the same password

In the actual use process, it is impossible to use only one place to use the password. Mailbox, QQ, MSN, Forum... It is extremely dangerous if the same password is reused everywhere. So as long as one of the corrections is deciphered, all the precautions will be ineffective. You can add a little flexibility in the process of setting different passwords. For example, the password I use normally is longzhong, then it can be set to qqlongzhong when used as QQ password, and longzhongsina can be used when setting as Sina email password.

VII. Change Passwords Frequently

This is also very important. No matter how complicated the password you set, as long as there is enough time, there is a possibility of being cracked. Therefore, it is very important to develop the habit of changing passwords on a regular basis. In the specific operation process, you can follow your own rules to replace. The password we used for the first time is qqlongzhong, the second one can put qq in the middle into longqqzhong, the third time can put qq in the back longzhongqq, etc.
