Recently, Yang-Wang-Chang proposed an improvement to Yang-Shieh's two password authentication schemes by using smart cards that can withstand a forged login attack. Yang-Wang-Chang's improved schemes, however, are still susceptible such attacks. Accordingly, the current paper demonstrates the vulnerability of Yang-Wang-Chang's schemes to these attacks and presents an improvements to resolve such a problem.
