Provided are an authentication method and an apparatus for the method. An authentication method includes generating, at a terminal, an identifier (ID)-based secret key using an ID of a user of the terminal and key generation factors exchanged with a server, encrypting, at the terminal, a password of the user using a symmetric key encryption algorithm taking the generated secret key as a symmetric key, and requesting authentication for the terminal user by transmitting the encrypted password to the server, and receiving, at the terminal, a response to the authentication request from the server.
