<p>A method for verifying a password at a user terminal in which a password and the URL of a page that is accessed when password authentication is successful are not easily revealed, is provided. In a user authentication system which carries out authentication at a user terminal via a network, a password authentication page where permission of authentication is determined based on a consistency between an input password inputted from the user terminal and an authentication password includes: a private page URL key obtained by transforming a private page URL which the user terminal can connect via the network if it is determined that the authentication is permitted and an authentication password, using an encryption algorithm; and a URL recovery processing code to find the private page URL by transforming the private page URL key and the input password through inverse transformation of the encryption algorithm. If it is determined that the authentication is permitted, the private page URL is acquired using the URL recovery processing code.</p> |
