摘要：Human being can remember graphical notations & signs, very easily & for a long time. The main aim of this paper is to build a mechanism for password so that our password become more secure, remembering durability & easy to create. We have implemented for multi-tier authentication system, because multi-tier authentication system is more secure than single level authentication system. We are using graphical symbols as password, So that user can remember multiple passwords for a long time. Obviously, if we are giving more facility to the user then we must more concern towards the security of the passwords. This is a mechanism to optimize between facilities & securities. Our main concern about security is to protect the user from Shoulder Surfing attack & Dictionary attack.
