To limit access to thieves of passwords, at initial registration with a Web server, a user is given a password and user name, and a cookie including a login key and machine ID is downloaded to the user. For subsequent log ins, the user inputs the user name and password and if they are correct, the server checks the cookie on the user computer to determine whether the login key and machine ID matches the record stored in the server before granting access. If access is successful a new login key is sent in a new cookie to be used in the next subsequent login so that the login key changes every login. If the cookie check is unsuccessful, the server refuses access until a user validation process has been completed.
