.. _access-control:

Access control
==============

Weblate comes with a fine-grained privilege system to assign user permissions
for the whole instance, or in a limited scope.

.. versionchanged:: 3.0

    Before Weblate 3.0, the privilege system was based on Django privilege system only,
    but is specifically built for Weblate now. If using anything older, please consult
    the documentation for the specific version you are using.

.. _access-simple:

Simple access control
---------------------

If you are not administrating the whole Weblate installation and just have
access to manage certain projects (like on `Hosted Weblate <https://hosted.weblate.org/>`_),
your access control management options are limited to following settings.
If you don’t need any complex setup, those are sufficient for you.

.. _acl:

Project access control
++++++++++++++++++++++

.. note::

    Projects running the gratis Libre plan on Hosted Weblate are always
    :guilabel:`Public`. You can switch to the paid plan if you want to restrict
    access to your project.

You can limit user’s access to individual projects by selecting a different
:guilabel:`Access control` setting. Available options are:

:guilabel:`Public`
   Visible to everybody.

   Any authenticated user can contribute.

   VCS repository might be exposed to everybody.

   **Choose this for open-source projects, or when your Weblate instance is private or locked-down.**
:guilabel:`Protected`
   Visible to everybody.

   Only chosen users can contribute.

   Only chosen users can access VCS repository.

   **Choose this to gain visibility, but still have control over who can contribute.**
:guilabel:`Private`
   Visible only to chosen users.

   Only chosen users can contribute.

   Only chosen users can access VCS repository.

   **Choose this for projects that should not be exposed publicly at all.**
:guilabel:`Custom`
   Visible only to chosen users.

   Only chosen users can contribute.

   Only chosen users can access VCS repository.

   Not available on Hosted Weblate.

   You will have to set up all the permissions using :ref:`custom-acl`.

   **Choose this on your own Weblate instance if you want to define access in a specific, finely customizable way.**

:guilabel:`Access control` can be changed in the :guilabel:`Access` tab of the
configuration (:guilabel:`Manage` ↓ :guilabel:`Settings`) of each respective
project.

.. image:: /screenshots/project-access.png

The default value can be changed by :setting:`DEFAULT_ACCESS_CONTROL`.

.. note::

    Even for `Private` projects, some info about your project will be exposed:
    statistics and language summary for the whole instance will include counts
    for all projects despite the access control setting.
    Your project name and other information can’t be revealed through this.

.. note::

    The actual set of permissions available for users by default in `Public`,
    `Protected`, and `Private` projects can be redefined by Weblate instance
    administrator using :ref:`custom settings <custom-acl>`.

.. seealso::

    :ref:`project-access_control`

.. _manage-acl:

Managing per-project access control
+++++++++++++++++++++++++++++++++++

Users with the :guilabel:`Manage project access` privilege (see
:ref:`privileges`) can manage users in projects via adding them to the teams.
The initial collection of teams is provided by Weblate, but additional ones can
be defined providing more fine-grained access control. You can limit teams to
languages and assign them designated access roles (see :ref:`privileges`).

The following teams are automatically created for every project:

For `Public`, `Protected` and `Private` projects:

Administration
    Includes all permissions available for the project.

Review (only if :ref:`review workflow <reviews>` is turned on)
    Can approve translations during review.

For `Protected` and `Private` projects only:

Translate
    Can translate the project and upload translations made offline.

Sources
    Can edit source strings (if allowed in the
    :ref:`project settings <component-manage_units>`) and source string info.

Languages
    Can manage translated languages (add or remove translations).

Glossary
    Can manage glossary (add or remove entries, also upload).

Memory
    Can manage translation memory.

Screenshots
    Can manage screenshots (add or remove them, and associate them to source
    strings).

Automatic translation
    Can use automatic translation.

VCS
    Can manage VCS and access the exported repository.

Billing
    Can access billing info and settings (see :ref:`billing`).

.. image:: /screenshots/manage-users.png

These features are available on the :guilabel:`Access control` page, which can be
accessed from the project’s menu :guilabel:`Manage` ↓ :guilabel:`Users`.

Team administrators
^^^^^^^^^^^^^^^^^^^

.. versionadded:: 4.15

Each team can have team administrator, who can add and remove users within the
team. This is useful in case you want to build self-governed teams.

.. _invite-user:

New user invitation
^^^^^^^^^^^^^^^^^^^

Also, besides adding an existing user to the project, it is possible to invite
new ones. Any new user will be created immediately, but the account will
remain inactive until signing in with a link in the invitation sent via an e-mail.
It is not required to have any site-wide privileges in order to do so, access management
permission on the project’s scope (e.g. a membership in the `Administration`
team) would be sufficient.

.. hint::

   If the invited user missed the validity of the invitation, they can set their
   password using invited e-mail address in the password reset form as the account
   is created already.

.. versionadded:: 3.11

  It is possible to resend the e-mail for user invitations (invalidating any
  previously sent invitation).

The same kind of invitations are available site-wide from the
:ref:`management interface <management-interface>` on the :guilabel:`Users` tab.

.. _block-user:

Blocking users
^^^^^^^^^^^^^^

.. versionadded:: 4.7

In case some users behave badly in your project, you have an option to block
them from contributing. The blocked user still will be able to see the project
if he has permissions for that, but he won't be able to contribute.

Per-project permission management
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can set your projects to `Protected` or `Private`, and
:ref:`manage users <manage-acl>` per-project in the Weblate user interface.

By default this prevents Weblate from granting access provided by
`Users` and `Viewers` :ref:`default teams <default-teams>` due to these teams’
own configuration. This doesn’t prevent you from granting permissions to those
projects site-wide by altering default teams, creating a new one, or creating
additional custom settings for individual component as described in :ref:`custom-acl` below.

One of the main benefits of managing permissions through the Weblate
user interface is that you can delegate it to other users without giving them
the superuser privilege. In order to do so, add them to the `Administration`
team of the project.

.. _custom-acl:

Custom access control
---------------------

.. include:: /snippets/not-hosted.rst

The permission system is based on teams and roles, where roles define a set of
permissions, and teams link them to users and translations, see
:ref:`auth-model` for more details.

The most powerful features of the Weblate’s access control system for now are
available only through the :ref:`Django admin interface <admin-interface>`. You
can use it to manage permissions of any project. You don’t necessarily have to
switch it to `Custom` :ref:`access control <acl>` to utilize it. However
you must have superuser privileges in order to use it.

If you are not interested in details of implementation, and just want to create a
simple-enough configuration based on the defaults, or don’t have a site-wide access
to the whole Weblate installation (like on `Hosted Weblate <https://hosted.weblate.org/>`_),
please refer to the :ref:`access-simple` section.

Common setups
+++++++++++++

This section contains an overview of some common configurations you may be
interested in.

Site-wide permission management
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To manage permissions for a whole instance at once, add users to
appropriate :ref:`default teams <default-teams>`:

* `Users` (this is done by default by the
  :ref:`automatic team assignment <autoteam>`).
* `Reviewers` (if you are using :ref:`review workflow <reviews>` with dedicated
  reviewers).
* `Managers` (if you want to delegate most of the management operations to somebody
  else).

You should keep all projects configured as `Public` (see :ref:`acl`), otherwise
the site-wide permissions provided by membership in the `Users` and `Reviewers` teams
won’t have any effect.

You may also grant some additional permissions of your choice to the default
teams. For example, you may want to give a permission to manage screenshots to all
the `Users`.

You can define some new custom teams as well. If you want to
keep managing your permissions site-wide for these teams, choose an
appropriate value for the :guilabel:`Project selection` (e.g.
:guilabel:`All projects` or :guilabel:`All public projects`).

Custom permissions for languages, components or projects
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can create your own dedicated teams to manage permissions for distinct
objects such as languages, components, and projects. Although these teams can
only grant additional privileges, you can’t revoke any permission granted
by site-wide or per-project teams by adding another custom team.

**Example:**

  If you want (for whatever reason) to allow translation to a
  specific language (lets say `Czech`) only to a closed set of reliable translators
  while keeping translations to other languages public, you will have to:

  1. Remove the permission to translate `Czech` from all the users. In the
     default configuration this can be done by altering the `Users`
     :ref:`default team <default-teams>`.

     .. list-table:: Group `Users`
         :stub-columns: 1

         * - Language selection
           - `As defined`
         * - Languages
           - All but `Czech`

..

  2. Add a dedicated team for `Czech` translators.

     .. list-table:: Group `Czech translators`
         :stub-columns: 1

         * - Roles
           - `Power users`
         * - Project selection
           - `All public projects`
         * - Language selection
           - `As defined`
         * - Languages
           - `Czech`

..

  3. Add users you wish to give the permissions to into this team.

As you can see, permissions management this way is powerful,
but can be quite a tedious job. You can’t
delegate it to another user, unless granting superuser permissions.

.. _auth-model:

Users, roles, teams, and permissions
++++++++++++++++++++++++++++++++++++

The authentication models consist of several objects:

`Permission`
    Individual permission defined by Weblate. Permissions cannot be
    assigned to users. This can only be done through assignment of roles.
`Role`
    A role defines a set of permissions. This allows reuse of these sets in
    several places, making the administration easier.
`User`
    User can belong to several teams.
`Group`
    Group connect roles, users, and authentication objects (projects,
    languages, and component lists).

.. graphviz::

    graph auth {

        "User" -- "Group";
        "Group" -- "Role";
        "Role" -- "Permission";
        "Group" -- "Project";
        "Group" -- "Language";
        "Group" -- "Components";
        "Group" -- "Component list";
    }

.. note::

  A team can have no roles assigned to it, in that case access to browse the
  project by anyone is assumed (see below).

Access for browse to a project
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A user has to be a member of a team linked to the project, or any component
inside that project. Having membership is enough, no specific permissions are
needed to browse the project (this is used in the default `Viewers` team, see
:ref:`default-teams`).

Access for browse to a component
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A user can access unrestricted components once able to access the components’
project (and will have all the permissions the user was granted for the
project). With :ref:`component-restricted` turned on, access to the component
requires explicit permissions for the component (or a component list the component is in).

.. _perm-check:

Scope of teams
^^^^^^^^^^^^^^^

The scope of the permission assigned by the roles in the teams are applied by
the following rules:

- If the team specifies any :guilabel:`Component list`, all the permissions given to
  members of that team are granted for all the components in the component
  lists attached to the team, and an access with no additional permissions is
  granted for all the projects these components are in. :guilabel:`Components`
  and :guilabel:`Projects` are ignored.

- If the team specifies any :guilabel:`Components`, all the permissions given to
  the members of that team are granted for all the components attached to the
  team, and an access with no additional permissions is granted for all the
  projects these components are in. :guilabel:`Projects` are ignored.

- Otherwise, if the team specifies any :guilabel:`Projects`, either by directly
  listing them or by having :guilabel:`Projects selection` set to a value like :guilabel:`All
  public projects`, all those permissions are applied to all the projects, which
  effectively grants the same permissions to access all projects
  :ref:`unrestricted components <component-restricted>`.

- The restrictions imposed by a team’s :guilabel:`Languages` are applied separately,
  when it’s verified if a user has an access to perform certain actions. Namely,
  it’s applied only to actions directly related to the translation process itself like
  reviewing, saving translations, adding suggestions, etc.

.. hint::

   Use :guilabel:`Language selection` or :guilabel:`Project selection`
   to automate inclusion of all languages or projects.

**Example:**

  Let’s say there is a project ``foo`` with the components: ``foo/bar`` and
  ``foo/baz`` and the following team:

  .. list-table:: Group `Spanish Admin-Reviewers`
         :stub-columns: 1

         * - Roles
           - `Review Strings`, `Manage repository`
         * - Components
           - foo/bar
         * - Languages
           - `Spanish`

..

  Members of that team will have following permissions (assuming the default role settings):

    - General (browsing) access to the whole project ``foo`` including both
      components in it: ``foo/bar`` and ``foo/baz``.
    - Review strings in ``foo/bar`` Spanish translation (not elsewhere).
    - Manage VCS for the whole ``foo/bar`` repository e.g. commit pending
      changes made by translators for all languages.

.. _autoteam:

Automatic team assignments
+++++++++++++++++++++++++++

On the bottom of the :guilabel:`Group` editing page in the
:ref:`Django admin interface <admin-interface>`, you can specify
:guilabel:`Automatic team assignments`, which is a list of regular expressions
used to automatically assign newly created users to a team based on their
e-mail addresses. This assignment only happens upon account creation.

The most common use-case for the feature is to assign all new users to some
default team. In order to do so, you will probably want to keep the default
value (``^.*$``) in the regular expression field. Another use-case for this option might be to
give some additional privileges to employees of your company by default.
Assuming all of them use corporate e-mail addresses on your domain, this can
be accomplished with an expression like ``^.*@mycompany.com``.

.. note::

    Automatic team assignment to `Users` and `Viewers` is always recreated
    when upgrading from one Weblate version to another. If you want to turn it off, set the regular expression to
    ``^$`` (which won’t match anything).

.. note::

    As for now, there is no way to bulk-add already existing users to some team
    via the user interface. For that, you may resort to using the :ref:`REST API <api>`.

Default teams and roles
++++++++++++++++++++++++

After installation, a default set of teams is created (see :ref:`default-teams`).

These roles and teams are created upon installation. The built-in roles are
always kept up to date by the database migration when upgrading. You can’t
actually change them, please define a new role if you want to define your own
set of permissions.

.. note::

   Site-wide privileges are not granted to any default role. These are
   powerful and quite close to superuser status. Most of them affect all projects
   in your Weblate installation.

.. _default-teams:

List of teams
^^^^^^^^^^^^^^

The following teams are created upon installation (or after executing
:wladmin:`setupgroups`) and you are free to modify them. The migration will,
however, re-create them if you delete or rename them.

`Guests`
    Defines permissions for non-authenticated users.

    This team only contains anonymous users (see :setting:`ANONYMOUS_USER_NAME`).

    You can remove roles from this team to limit permissions for
    non-authenticated users.

    Default roles: `Add suggestion`, `Access repository`

`Viewers`
    This role ensures visibility of public projects for all users. By default,
    all users are members of this team.

    By default, :ref:`automatic team assignment <autoteam>` makes all new
    accounts members of this team when they join.

    Default roles: none

`Users`
    Default team for all users.

    By default, :ref:`automatic team assignment <autoteam>` makes all new
    accounts members of this team when they join.

    Default roles: `Power user`

`Reviewers`
    Group for reviewers (see :ref:`workflows`).

    Default roles: `Review strings`

`Managers`
    Group for administrators.

    Default roles: `Administration`

.. warning::

    Never remove the predefined Weblate teams and users as this can lead to
    unexpected problems! If you have no use for them, you can removing all their
    privileges instead.

Additional access restrictions
------------------------------

If you want to use your Weblate installation in a less public manner, i.e. allow
new users on an invitational basis only, it can be done by configuring Weblate
in such a way that only known users have an access to it. In order to do so, you can set
:setting:`REGISTRATION_OPEN` to ``False`` to prevent registrations of any new
users, and set :setting:`REQUIRE_LOGIN` to ``/.*`` to require signing in to access
all the site pages. This is basically the way to lock your Weblate installation.

.. hint::

    You can use built-in :ref:`invite-user` to add new users.
