Three principles for creating computer security passwords

        First: Please set a complex password. Since it is a password, security is the first. If we know that our password is a password that a hacker can crack at any time, what is the significance of setting it? Specifically, the number of digits of the password password should be 8 to 12 digits. The combination of letters and numbers should be used, and regular letters or numbers should be avoided to avoid the use of alphanumeric characters at the beginning or end. Second: ensure easy to remember In general, case switching can easily lead to confusion, and passwords that are too strict without rules are easy to forget. In general, the combination of “uppercase or lowercase letters + numbers” is sufficient, and pinyin can be more easily remembered. Third: focus on the application environment Do not think that the design of the password password combination is 100% safe enough, the system or software environment it is applied to is also a factor that cannot be ignored. Due to the limitations of early development techniques and concepts, some systems or software that use password passwords have design security flaws that make it difficult to crack passwords in their specific application environment. Therefore, in this case, even if the password combination designed by the user is complicated, it is not helpful. Therefore, it is recommended that the user use two sets of password and password combinations in actual applications, which are respectively used for different applications of weak passwords and strong password systems or software, in order to prepare for the whole.
