Abstract
A password hardening system is arranged between one or more clients and a domain controller or other authentication entity. The password hardening system comprises a plurality of servers configured to store in a distributed manner respective shares of at least one of a hardened surrogate password and a corresponding user password. The password hardening system is configured to intercept a first set of one or more communications based at least in part on the user password and directed to an authentication entity external to the password hardening system, and to provide to the authentication entity in place of at least a portion of the intercepted first set of one or more communications a second set of one or more communications based at least in part on the hardened surrogate password. The password hardening system may be configured to serve as a proxy between an authenticating client and the authentication entity.
