Description:

This Application(SAS-WS) offers One Time Password (OTP), services for multifactor authentication. OTPs serve as a Second Factor in a Two-Factor Authentication protocol. The primary interface between applications and SAS is a SOAP based Webservices’ Interface.

OTP Authentication which is integral component of a two-factor authentication scheme provides enhanced security by making use of “What- you -have” module. This security scheme is well suited for today’s environment because of the proliferation of smart phones and other hand held smart devices. When using SAS-WS, the first factor is typically a password, which is managed independently by each of our client. The Second factor is a security code generated by a token. Client application which make use of SAS-WS enhance the security of their systems by requiring their users two provide as usual password plus unique security code. whenever they require access to a protect resource.
