Information
Password hints are user-created text displayed when an incorrect password is used for an account.
Rationale:
Password hints make it easier for unauthorized persons to gain access to systems by displaying information provided by the user to assist in remembering the password. This info could include the password itself or other information that might be readily discerned with basic knowledge of the end user.
Impact:
The user can set the hint to any value, including the password itself or clues that allow trivial social engineering attacks.
