# Inviting Members

To join an existing Arnica tenant, users must be invited. Any member of the tenant can add new users through the **Admin → Security → Users & Roles** page.

## How to invite a member

1. Navigate to **Admin → Security → Users & Roles**.
2. Enter the user's email address in the **Email** field.
3. Click **Invite**.

The invited user will receive a welcome email with a personalized link to set their password. Once they sign in, they will be redirected into your tenant.

For full details on managing users, roles, and permissions, see [Users & Roles](/arnica-documentation/platform-operations/security/users-and-roles.md).

## Supported permissions

Owners can invite additional members. Invited members can perform all administrative tasks except inviting additional members.

## Tenant membership

Each Arnica user can only belong to one tenant at a time. If a user needs to move to a different tenant, they must leave their current one first via **Profile menu → Edit Account → Leave**.
