To increase the strength of user-chosen passwords, users are typically required to adhere to a set of rules known as password guidelines when creating passwords. Users compose their passwords following the specific requirements given in the guidelines. For example, the password must contain at least eight characters including at least one number or one upper case letter, and it should not contain the username. There are various password guidelines that are used by organisations, and they should be written efficiently to provide adequate security levels in the organisations [7, 52].
There are more studies which present the different ways to generate a mnemonic password. Vu et al. [57] used two mnemonic password generation methods in a user study, and let all users choose their own sentence. As the passwords created with the mnemonic string method typically have more characters, they were thought more secure. However, the authors found little difference in password creation times, login times and recall error rates between two methods. In a previous study, they had also found that passwords which contain more characters were more resistant to cracking [47]. Unfortunately, as the way of substitute words and characters suggested in the study is well known by attackers, mnemonic string method may not be very much secure as previously thought.

Passwords authentication mechanisms mostly involve a trade-off between security and usability. The main reason of the imbalance between them is memorability problem. When users are forced to create long, complex and randomly generated passwords, they are likely to write them down or forget them. On the other hand, when users choose the weak and predictable passwords, they are susceptible to attacks. The researchers who tried to crack passwords conducted several experiments and the results proved the weaknesses of the user-chosen passwords [25, 36]. It seems more secure password means the less usable password or vice versa [5]. Some authors investigated the relationship between password security and usability by conducting several studies [31].
According to the results, people are not good at predicting the strength of their own passwords. As Fig. 5 indicates that neither in the control group (\(t (93) = -1.375\), \(p =0.172\)) nor in the experimental group (\(t (140) = 0.034\), \(p = 0.973\)) there were difference in terms of password strength between those who thought their passwords were hard to crack and those who thought their passwords were easy to crack.
There is a lack of ecological validity in generalising the findings to real life as the study is not conducted with a real application in use. The participants knew that the websites were created for a research study and they created passwords for helping the study. If users created passwords for a real website to perform their own tasks, quality of the passwords and compliance with the guidelines might have been different. On the other hand, the password guideline including several password creation tips provided to the experimental group is somewhat long to read. Therefore, users might not be willing to read it when they create a password in real life. This reduces the practicability of the proposed guideline. Another issue about the study is the unusual demographics of the experimental group. The participants were randomly assigned to the experimental and control groups. However, number of the participants who have high education level in the experimental group is more than the control group. This situation might have affected the password strength rates in the experimental group. 2ff7e9595c
