Abstract
A method of in-line sign in that allows a user to sign into a first server based on a sign-in methodology of a second server is disclosed. The method uses, among other things, a nonce and approved URL list to prevent spoofing and replay attack. Additionally, the method allows error messages that occur during the authentication process to be displayed to the user having the look and feel of the first server, despite using the authentication process of the second server. A method of dual or distributed authentication is also disclosed wherein the user need only to input the login id and password once and wherein the two authentication processes need not exchange the user's password.
