Creative password setting and security of letter lock
I. Introduction
In modern society, with the development of network and the enhancement of people's awareness of privacy protection, password has become an important authentication method. Among all kinds of passwords, letter lock is deeply loved by users because of its convenience and strong plasticity.
Second, the letter lock password characteristics analysis
1. Strong visibility: compared with numeric keyboard input, letter lock is more intuitive, which enables users to clearly see their own drawings;
2. Easy to remember: Compared with the password composed of pure words or numbers, it is easier to remember the trajectory with fingers;
3. Hard to guess: Because you can freely choose the starting point and ending point every time you unlock it, it is difficult to completely copy it even if the bystander sees the whole process.
4. Personalization: Each user can set unique and personalized patterns as account login credentials according to his own preferences.
Third, how to improve the security of letter locks?
Although most smart phones in the market have supported many more advanced and efficient authentication methods, such as fingerprint identification and even facial ID, the traditional "circle-drawing" unlocking method-the so-called "letter lock" is still needed in some occasions. In order to ensure that personal information is not stolen, the following are some practical tips:
(1) Avoid using too simple and repetitive line combinations (such as horizontal lines and vertical lines, etc.), because these common shapes are easy to be guessed by others and tried to crack;
(2) Increase the complexity, such as changing the original simple continuous straight line into a path with a corner or an arc turning point, thus improving the difficulty of cracking;
(3) Change the password mode regularly, and don't use the same pattern for a long time, so as not to form a habit and be stolen after being remembered;
(4) Combined with other authentication mechanisms, such as turning on the two-factor authentication function on the device, even if others know your unlocking pattern, they can't directly enter the system.
IV. Conclusion
To sum up, through the above methods, we can effectively improve the overall security level of the letter lock itself and the account information behind it, but it should be noted that no technical means can achieve 100% insurance, so it is suggested that everyone should strengthen their awareness of information security and develop good usage habits.
