Disclosure of Personal Information in Passwords on Social Media

Today, social media and the Internet have become a major part of people's daily lives. As a result, most users post personal information such as birthdays, interests and family members' names on social media. Since users often use their personal information when creating their password, their personal information published on social media can be used to find out users' passwords. Based on this idea, we investigate how many people have disclosed their password or part of their password in their social media account. Using the social media profiles of the individuals, a list of candidate passwords has been created, followed by matching the candidate passwords with the existing password in the database using different metrics.
