# Tenant management

> Tenant Administrator guide for ABBYY Vantage: manage users and roles, configure authentication, and adjust tenant-level settings.

A **tenant** is an isolated ABBYY Vantage workspace with its own users, skills, and settings. As a Tenant Administrator, you manage who can access the tenant, how they sign in, and how the tenant itself is configured.
