Real websites review

 

To evaluate the performance in real life, we used them to generate passwords for 10 websites chosen randomly from Dumb-password-rules.

We ran ten times for each password generator for each website. If all passwords were good, it would get 10 stars. It would lose 1 star for one unqualified password, two stars for two unqualified passwords, and so on. They might also lose extra stars due to its comeplex setup for the website.

Discussion

 

Although we made an effort to have a professional review, we cannot guarantee its accuracy due to the limitation of the review for various reasons. We hope to discuss it with you and improve the review together.

 

Limitation

There are no standards for assessing password generators. To create secure, strong, and suitable passwords, we have considered website requirements, experts’ suggestions, and users’ needs when gathering review features. Nevertheless, some features might still be missed.

As we all know, the conclusion would be more convincing if more websites were reviewed. However, due to the time limit, there are only ten websites in this review. Therefore, the review result might need to be more accurate, but it did show the real performance of these password generators since ten websites were randomly chosen.

The features are not equal. Some are more important than others. For example, the feature of password managers to generate suitable passwords was much more critical than the user-friendly setting. We cannot find data to weigh each feature. It is a highly complex topic. For simplicity, we just calculated the average.

Although having followed specific rules, passwords are generated randomly, meaning that users might get different results even if they use the same password managers and follow the same rules. Take Bitwarden as an example, it does not allow users to exclude(%) in passwords. When users try to generate passwords for Admiral with Bitwarden, they might get less than or more than four qualified passwords.

Of course, if we ran 100 times, the results would be more accurate. But the results based on 10 times’ test were still convincing. Since each website weighted only 10%, it would not be a big problem

Everyone has their preferences, and this can affect their thought. The reviewers’ preferences also affected the review results, although we strictly followed the gathered features.

 

Do you agree with the review features, results, and methodology? Are there any websites you need help generating suitable passwords? Please let us know if you have any ideas about the password generator.

An interesting finding: Repeated or descending numbers?
 

During the review, we also had an interesting finding.

Unfortunately, no password generators can generate suitable passwords for websites like Ameli.fr (French national health insurance). Although Zero Password Manager and KeePassium can limit the continuous repeat characters, they do not stop using the descending numbers or restrict the times of repeating the same numbers in passwords.

This won’t be a big problem since few websites require a long password only consisting of digits. Meanwhile, most password generators generate passwords randomly with three kinds of characters(letters, digits, and special characters) and thus do not generate passwords with repeated or descending numbers. But it might be nice to see such a password manager with these features for those with accounts of Ameli.fr (French national health insurance).

 

Conclusion

 

This review aimed to find the best free password generator of password managers and showed every password manager has pros and cons. The present review clearly shows that Zero Password Managers effectively generate passwords quickly, especially for those dumb websites. KeePassXC, KeePassDX, KeePassium, and Enpass follow below since they also allow users to choose specific unique letters. Next comes LastPass and Bitwarden. If you want an online password manager, Enpass would be better. We also need aware that the result might not be very accurate because it was based on a limited number of websites reviews.
