The authentication system uses passwords to authenticate user login and stores the password in a central server. The central server is easily prone to attack and if they are being compromised by the intruder, it is possible for the intruder to obtain the password and gain access to the contents of the user. To overcome this problem, the multi-server systems were being proposed in which the user has to communicate in parallel with several or all of the servers for the purpose of authentication. Multi-server system requires a large communication bandwidth and needs for synchronization at the user. To overcome these problems the two server authentication system proposed here uses only passwords and the session keys rather than performing any cryptographic techniques.
