A centralized password repository (CPR) provides network users with a password portal through which the user can manage password access to domains and applications on the network. A subset of the domains and applications on the network may be required, by design, to maintain a separate password infrastructure. For these systems, the CPR establishes a secure and authenticated communication channel and software on the system interfaces with the password infrastructure to synchronize the password in the system password infrastructure with the password in the CPR. For other systems not required to maintain a separate password infrastructure, the CPR performs password services by responding to requests from those systems seeking to validate user IDs and passwords. The CPR enables an administrator to modify network privileges and enables a user to alter passwords on the network through a single interface.
