Patent abstract
This document describes tools that constrain a login to a subset of access rights. In one embodiment, the tools generate a constrained password by executing a cryptographic algorithm on a user ID, general password, and one or more desired constraints. The constrained password is used in place of the general password to gain access rights that are a subset of the access rights that would be granted if the general password were used instead.
