334 – Avoid knowledge-based authentication

Summary

Password hints and knowledge-based authentication, such as secret questions, should not be enabled.

Description

Password hints often offer enough information for an attacker to guess a users password. Answers to secret questions are sometimes information that is publicly available or that can be found on social media. Therefore, these mechanisms should not be part of the authentication process and should not be used in the password recovery process either.
