Abstract:
Authentication is the process of verifying a user’s identity when the user is requesting services from any secure IT system, the default for all user logons whether local or remote has always been reliant upon the humble password, in the past this has been good enough, but now days that we used to conduct our world and business using password for authentication is not secure any more.
A more secure method is this thesis proposed the two-factor authentication that verifies not only the username/password pair, but also requires a second factor to authenticate.
The proposed method is been implemented using asp.net and java android, this method is been analysis for most know attack and the result obtain is reasonable in term of security attack.
technical application is been developed that provides a high level of protection through the use of a two factor authentication mechanism via one time password technology, where the first factor is the user name and password, and the second factor is the generated one time password by smartphonephone
