## Permissions

InvenTree provides access control to various features and data, by assigning each *user* to one (or more) *groups* which have multiple *roles* assigned.

!!! info "Superuser"
    The superuser account is afforded *all* permissions across an InvenTree installation. This includes the admin interface, web interface, and API.

### User

A *user* is a single unique account with login credentials. By default, a user is not afforded *any* permissions, and the user must be assigned to the relevant group for the permissions to be assigned.

### Group

A *group* is a named set of zero or more users. Each group is assigned permissions against each possible role.

### Role

A *role* is a set of distinct permissions linked to a given subset of InvenTree functionality (more on this below).

## Roles

InvenTree functionality is split into a number of distinct roles. A group will have a set of permissions assigned to each of the following roles:

| Role | Description |
| ---- | ----------- |
| **Admin** | The *admin* role is related to assigning user permissions. |
| **BOM** | The *bom* role is related to accessing Bill of Materials data |
| **Build** | The *build* role is related to accessing manufacturing / Build Order |
| **Part** | The *part* role is related to accessing Part data |
| **Part Category** | The *part category* role is related to accessing Part Category data |
| **Purchase Order** | The *purchase* role is related to accessing Purchase Order data |
| **Return Order** | The *return* role is related to accessing Return Order data |
| **Sales Order** | The *sales* role is related to accessing Sales Order data |
| **Stock Item** | The *stock item* role is related to accessing Stock Item data |
| **Stock Location** | The *stock location* role is related to accessing Stock Location data |

### Role Permissions

Within each role, there are four levels of available permissions:

| Permission | Description |
| ---------- | ----------- |
| **View** | The *view* permission allows viewing of content related to the particular role |
| **Change** | The *change* permission allows the user to edit / alter / change data associated with the particular role |
| **Add** | The *add* permission allows the user to add / create database records associated with the particular role |
| **Delete** | The *delete* permission allows the user to delete / remove database records associated with the particular role |

## Dangerous User Flags

In addition to the above permissions, there are two special flags that can be assigned to a user:
- **Staff** - A user with the *staff* flag is able to access the admin interface, and can trigger dangerous actions that might have a security impact such as changing parsable files on the server (templates / reports / plugins). Some of these actions require the *admin* role to be assigned as well.
- **Superuser** - A user with the *superuser* flag is able to access and change all data and functions of InvenTree. A superuser can modify and access all data that the InvenTree installation / server has access to - including shell access on the server OS itself. This is a very powerful flag, and should be used with caution.

It is strongly recommended to register any users with staff / superuser flags with strong MFA methods to reduce the risk of unauthorized access. These accounts should be used with caution, and should not be used for day-to-day operations.

Practicing account tiering is strongly recommended.


## Admin Interface Permissions

If a user does not have the required permissions to perform a certain action in the admin interface, those options not be displayed.

If a user is expecting a certain option to be available in the admin interface, but it is not present, it is most likely the case that the user does not have those permissions assigned.

## Web Interface Permissions

When using the InvenTree web interface, certain functions may not be available for a given user, depending on their permissions. In this case, user-interface elements may be disabled, or may be removed.

## API Permissions

When using the InvenTree API, certain endpoints or actions may be inaccessible for a given user, depending on their permissions.

As the API is used extensively within the web interface, this means that many data tables may also be impacted by user permissions.
