* Self-service requests for access.
* Delegated administration of identities and access rights.
* Access certification, both periodic and event triggered.
* Synchronizing identity attributes and passwords across systems.
* Detecting and remediating unauthorized access changes.
* Self-service credential management -- password and PIN reset, security question enrollment, etc.
* Randomizing and securely storing passwords to shared, privileged accounts.
* Temporary privilege elevation, via password injection, group membership or SSH trust.
* Privilege login session recording and playback.
* Replacing embedded, static and/or plaintext passwords with secure API calls.
* Periodically changing and injecting Windows service account passwords.
