Abstract: A networks system can solve computational problems it can coordinate the use of shared resources or data and also provide communication services to client and server. In network client server communication who shares the password, check the process of communication between them and meanwhile establish a cryptographic key by exchange of messages and information. A client will store a password mutually in the one server and If that server failed for authentication, the unauthorized access may happen. In this study, researchers consider two servers cooperate to authenticate a client and if one server is failed for authentication, the attacker still cannot access the client information from the failed or compromised server. A two server password authenticated key exchange is parallel in the manner that two peer server equally put up to for the authentication.
