# User management

> Add, remove, and manage users in your ABBYY Vantage tenant, and control what they can do by assigning Role-based access control (RBAC) roles.

As a Tenant Administrator, you decide who has access to your Vantage tenant and what they're allowed to do once they're in. User management covers two tasks: maintaining the list of users in the tenant and assigning the roles that grant their permissions.

<Note>
  You need the **Tenant Administrator** role to perform these tasks.
