How to set up a safe and secure password when using a computer

In the process of using the computer, we are always dealing with the password. Many hackers have successfully stolen QQ, cracked mailboxes, because we set the password is too simple. If you set the password by others to guess or decipher, then will be important information, personal privacy is leaked. So how to set a secure password is a big event related to each. Below we will introduce to you in the process of setting the password must comply with 10 rules.

One, as long as possible

In general, passwords are required to be set not less than 6 digits. This shows that less than 6 digits of the password is very cracked. From the point of view of password cracking, the most common method is brute force, one of the most typical features of brute force cracking is the mathematical arrangement of the characters that may be used, and each of them is tested until the correct password is found. If we increase the number of digits, a friend who understands the mathematical permutation will know how many permutations are created for each additional 1 bits. Therefore, the password as long as possible is the first we have to comply with the first rule. Even more than 6 bits use repetitive characters to increase the difficulty of deciphering.

Second, as unfamiliar as possible

Many users like to use their own names, nicknames, birth dates, phone numbers, or other words that use a higher frequency as the content of the password. We all know that contradictions are often generated internally, within the company, this information is often well-known. This way, when you enter a password, someone can guess the contents of the password just by paying a little attention. Therefore, if you are worried that the password you set is not easy to remember, then you can add some characters that are only known to you before and after the password in order 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 out. In fact, simple numbers and characters can easily be deciphered. Therefore, when we set the password to include letters, numbers, various symbols, if case-sensitive, then should also use the case, the composition of the password will be much more secure.

Four, from the back to the previous order

When you set up a password, the habit of the average person is to start with a small sequence of a, B, C, D, or 1, 2, and 3, which just satisfies the sequence of brute force cracking, because they are calculated according to the natural ordering of letters and numbers. Therefore, if we set the first bit of the password to Z and so on, then the probability of cracking is much less.

Five, easy to forget the password

Both the password is long enough to require enough complexity, so that although the hacker can prevent, but also to their own input a lot of trouble. If time is longer, it is easy to forget, to bring inconvenience to use. In fact, you don't have to worry about it, you can use what you're familiar with when you set up your settings, and then put a character on the front and back of the password you set. You can also use more than one familiar content to overlay, for example, his nickname plus the number of phone numbers and mobile phones after the three digits, such as their own primary school name plus the last letter of name, and so on, this type of password is familiar to them, there is no forgotten the concern, but also played a paralytic to others.
