Passwords are the most common authentication mechanism “something user know” that defenses against unauthorized access to com puters and personal information. Another common authentication mechanism is bio-metrics credential “something user are” like Face-id, Fingerprint, Voice recognition. However, due to the nature of biometrics that users do not create or remember it. Biometrics being more convenience then, users stop using passwords for a while. With increase online accounts’ number and password complexity rules, users struggle to create a different password for each account and remember each one that created differently. Consequently, for these challenges, there has been increasing in insecure users’ behaviors such as using predictable data, personal information, dictionary words, or a unified password. These habits expose users and organizations to intensive risk. Password memorability increasing is an important factor to reduce users’ insecure behaviors. A survey was conducted to measure the effect of using biometrics for a while on the ability to remember passwords and found that the majority of users were affected and would like to user a method to help them generate password. So, VowPass was proposed to facilitate secure password generation which not only improved memorability but also reduces the chances of a successful dictionary and brute attack.45en-USBiometricsMemorabilityDictionary AttackThesis
