What this post added

This post analyzes the security risks associated with partial password validation, demonstrating through simulations that it offers negligible protection against credential stuffing attacks. It highlights that this practice often indicates insecure password storage and incentivizes password reuse. The post advocates for multi-factor authentication (MFA) as a superior alternative for account security, contrasting it with the limitations of SMS-based one-time passwords.
