# Backend API 18.1.1

### New Features

* New dedicated API for retrieving Non-Human Identity (NHI) details, providing categorized visibility into PAM users, resources, gateways, and KSM devices
* Introduced a tiered KSM API usage model for PAM accounts, replacing the previous unlimited allocation with structured tier levels (Default, Tier 1, Tier 2, Tier 3, Enterprise)
* Separate KSM NHI count is now tracked alongside the existing PAM NHI count
* New security audit event to track when a user reveals a password on a record

### Tasks

* **KA-8648:** New API endpoint to retrieve and categorize Non-Human Identity (NHI) UIDs. Returns distinct NHI identifiers grouped by type - PAM users, resources, gateways, and KSM devices - enabling admins to inspect and verify NHI counts directly from the Admin Console.
* **KA-8553:** PAM add-on activation now assigns a default PAM-bundled KSM tier. This introduces structured tier-based KSM usage tracking for all PAM accounts, supporting future billing and overage visibility.
* **KA-8675:** New audit event 'revealed password' is now generated when a user reveals a password on a Keeper record. This event is logged for security monitoring and is available through SIEM/syslog integrations.
