摘要：In this study, the issues and causes related to sending One Time Password (OTP) via SMS are examined
and analysed. One-time password (OTP) is password that validates an authentic user for only one login to the
respective system. If user is unauthorized, system will not allow further access. OTP can be generated by using
different cryptographic hash functions that provides a fixed string which can be used as second level security [1]. In
generation of OTP there are many factors that can make OTP unique every time it is generated. In this report, the flow
of system I am developing, topics related to issues and causes, about OTP over SMS. One Time Passwords (OTP) is
introduced to provide an additional layer of security. OTP is normally transmitted through SMS, but recent studies
prove that OTPs over SMS are causing various issues and causes which lead time delay in transaction [6].
