Information
Password hints help the user recall their passwords for various systems and/or accounts. In most cases, password hints are simple and closely related to the user's password.
Rationale:
Password hints that are closely related to the user's password are a security vulnerability, especially in the social media age. Unauthorized users are more likely to guess a user's password if there is a password hint. The password hint is very susceptible to social engineering attacks and information exposure on social media networks
Solution
