Abstract: Security concerns are on the rise in all areas such as banks, governmental applications, healthcare industry, military organization, educational institutions. Government organizations are setting standards, passing laws and forcing organizations and agencies to comply with these standards with non-compliance being met with wide-ranging consequences. There are several issues when it comes to security concerns in these numerous and varying industries with one common weak link being passwords. Most systems today rely on static passwords to verify the user’s identity. However, such passwords come with major management security concerns. Users tend to use easy-to-guess passwords, use the same password in multiple accounts, write the passwords or store them on their machines. Further more, hackers have the option of using many techniques to steal passwords such as shoulder surfing, snooping, sniffing, guessing. Several ‘proper’ strategies for using passwords have been proposed. Some of which are very difficult to use and others might not meet the company’s security concerns. Two factor authentication using devices such as tokens and ATM cards has been proposed to solve the password problem and have shown to be difficult to hack. Two-factor authentication (T-FA) or (2FA) is a system wherein two different factors are used in conjunction to authenticate. The proposed method guarantees that authenticating to services, such as online Shopping, is done in a very secure manner. The system involves using a OTP (One Time Password) Algorithm generation of Dynamic password for second way of authentication. One time password uses information sent as an SMS to the user as part of the login process.
