A remote password authentication scheme based on a circle is proposed in this paper. In this scheme, we use some simple tangent theorem like secant tangent theorem to authenticate the user and the server. The security of this scheme depends on the tangent points located in a plane associated with the circle and tangent line. In our scheme, a legal user can freely choose and change his password using his smart card.
