# User Manual

Each version of emCA includes user manuals covering four key roles: 

CA Administrator, 

Administrator, 

Officer, and 

Auditor. 

These manuals provide details such as login, application setup, screenshots, features, functionalities, and the roles and responsibilities associated with each user. They serve as a reference to help users understand and perform their tasks within the application.

{% hint style="info" %}
Until version V4.2.3, emCA included a separate role called *Operator*. This role was responsible for managing the CA hierarchy (including viewing and exporting Root and Sub-root CA certificate details) and performing secure data backups using manual (local) or automatic (local/remote) modes. From version V4.2.4 onwards, these responsibilities have been merged into the *CA Administrator* role.
