# Administration

The **Admin** area (`/admin`) is exclusively accessible to admins.
Without the admin role, access is denied.

> At the top right, the **Redundancy dashboard** button leads to the automatic
> duplicate detection (see [Redundancy](/docs/handbook/redundanz)).

## "Users" tab

Management of local accounts.

- **Add user:** username (required), password (at least 6 characters),
  email (optional), **role** (User/Admin), **plan** (Free/Premium/Enterprise).
- **Edit user:** set role, plan and (for local accounts) a new password.
  For OIDC accounts, password management is offered in the identity provider
  (e.g. Keycloak).
- **Delete user:** permanently removes the account (not for your own account).

API reference:
[`POST /users`](/docs/reference/endpoints/users#createUser),
[`PATCH /users/{id}`](/docs/reference/endpoints/users#updateUser),
[`DELETE /users/{id}`](/docs/reference/endpoints/users#deleteUser).

## "Tools" tab

Central access to the tool catalog.

- **Search** for tools.
- View, edit or move individual tools to the trash.
- **Bulk action:** select multiple tools and move them to the trash
  (confirmation dialog; soft-deleted tools are removed from all public views
  and can be restored or permanently deleted).

## "Audit log" tab

Chronological log of all creation, change and deletion operations
(max. 100 entries): action, entity + ID, timestamp, executing person and
changed fields.

API reference: [`GET /audit-logs`](/docs/reference/endpoints/audit#listAuditLogs).

## "System" tab

Version information of the running instance:

- **Version** (e.g. `v0.8.1`),
- **Commit** (7-digit SHA, linked to the repository),
- **Build date**,
- **Trash retention** ("N days" or "Forever").

## Tool links (Admin)

On the detail page of a tool you can manage **links** as an admin
(own/"manual" as well as automatically detected ones):

- **Link tool:** dialog with tool ID, **relationship type**
  (Similar / Replaces / Superseded by) and optional notes.
- Relationship types are displayed as badges on the detail page.
- Manual links can be removed again via the trash icon.
