# Permissions

Users have different abilities depending on the access level they have in a
particular group or project. If a user is both in a group's project and the
project itself, the highest permission level is used.

On public and internal projects the Guest role is not enforced. All users will
be able to create issues, leave comments, and pull or download the project code.

GitLab administrators receive all permissions.

To add or import a user, you can follow the [project users and members
documentation](../workflow/add-user/add-user.md).

## Project

The following table depicts the various user permission levels in a project.

[^2]: Not allowed for Guest, Reporter, Developer, Master, or Owner

## Group

Any user can remove themselves from a group, unless they are the last Owner of
the group. The following table depicts the various user permission levels in a
group.

| Action                  | Guest | Reporter | Developer | Master | Owner |
|-------------------------|-------|----------|-----------|--------|-------|
| Browse group            | ✓     | ✓        | ✓         | ✓      | ✓     |
| Edit group              |       |          |           |        | ✓     |
| Create project in group |       |          |           | ✓      | ✓     |
| Manage group members    |       |          |           |        | ✓     |
| Remove group            |       |          |           |        | ✓     |

## External Users

In cases where it is desired that a user has access only to some internal or
private projects, there is the option of creating **External Users**. This
feature may be useful when for example a contractor is working on a given
project and should only have access to that project.

External users can only access projects to which they are explicitly granted
access, thus hiding all other internal or private ones from them. Access can be
granted by adding the user as member to the project or group.

They will, like usual users, receive a role in the project or group with all
the abilities that are mentioned in the table above. They cannot however create
groups or projects, and they have the same access as logged out users in all
other cases.

An administrator can flag a user as external [through the API](../api/users.md)
or by checking the checkbox on the admin panel. As an administrator, navigate
to **Admin > Users** to create a new user or edit an existing one. There, you
will find the option to flag the user as external.

By default new users are not set as external users. This behavior can be changed
by an administrator under **Admin > Application Settings**.

## GitLab CI

GitLab CI permissions rely on the role the user has in GitLab. There are four
permission levels it total:

- admin
- master
- developer
- guest/reporter

The admin user can perform any action on GitLab CI in scope of the GitLab
instance and project. In addition, all admins can use the admin interface under
`/admin/runners`.
