Abstract
A method and apparatus for updating the password status of one or more servers in a client/server environment utilizes multiple passwords associated with a client process, including a current password and one or more non-current passwords. Each password has associated therewith a key and a key identifier. If upon an attempted access, a server process challenges the client process with a non-current key identifier, the client process provides the corresponding key associated with the non-current password. Once access to the server is achieved, the key identifier associated with the current password is supplied to the server process by the client process. In a networked server environment, the updated server process may provide the updated key identifier to other server processes which have knowledge of the client profile.
