Abstract
Embodiments of the present invention provide a method, a client and a token for providing a nonce during a login associated with the token in a multi-user computer system. A login process is activated after token insertion by a request to execute a user privileged operation made by a client application process. If a password provided to the login process by an access requester associated with authorized use of the token is validated in the token, a nonce is generated in the token. The password is passed to the token in a command and the nonce is passed to the client application process in a response to the command. The nonce is used by the client application process or any other additional processes during execution of the user privileged operation. Additional nonces, including those based on security level can be generated and passed to additional client application processes as execution of user privileged operations is requested.
