Two server PAKE (Password Authentication Key Exchange) use symmetric solution to authenticate client in client server authentication system. This system have advantage that encrypted password get store in two servers instead of single server to minimize disadvantage of single server system. Both the server communicates and exchange messages to authenticate client. OPT (One Time Password) is also a secure solution which uses random function to generate password and this password get discard after one use. In this paper, two servers PAKE and OTP protocol is combining to overcome drawback of previous systems and provide more security.
