+Simple auth manager
+===================
+
+.. note::
+    Before reading this, you should be familiar with the concept of auth manager.
+    See :doc:`apache-airflow:core-concepts/auth-manager/index`.
+
+.. warning::
+  The simple auth manager is intended to be used for development and testing purposes. It should not be used in production environment.
+
+The simple auth manager is the auth manager that comes by default in Airflow 3. As its name suggests,
+the logic and implementation of the simple auth manager is **simple**.
+
+Manage users
+------------
+
+Users are managed through the `webserver config file <https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#config-file>`__.
+In this file, the list of users are defined in the constant ``SIMPLE_AUTH_MANAGER_USERS``. Example:
+
+.. code-block:: python
+
+  SIMPLE_AUTH_MANAGER_USERS = [
+      {
+          "username": "admin",
+          "role": "admin",
+      }
+  ]
+
+Each user needs two pieces of information:
+
+* **username**. The user's username
+* **role**. The role associated to the user. For more information about these roles, :ref:`see next section <roles-permissions>`.
+
+The password is auto-generated for each users and printed out in the webserver logs.
+When generated, these passwords are also saved in your environment, therefore they will not change if you stop or restart your environment.
+
+.. _roles-permissions:
+
+Manage roles and permissions
+----------------------------
+
+There is no option to manage roles and permissions in simple auth manager. They are defined as part of the simple auth manager implementation and cannot be modified.
+Here is the list of roles defined in simple auth manager. These roles can be associated to users.
+
+* **viewer**. Read-only permissions on DAGs, assets and pools
+* **user**. **viewer** permissions plus all permissions (edit, create, delete) on DAGs
+* **op**. **user** permissions plus all permissions on pools, assets, config, connections and variables
+* **admin**. All permissions
+
+Optional features
+-----------------
+
+Disable authentication and allow everyone as admin
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This option allow you to disable authentication and allow everyone as admin.
+As a consequence, whoever access the Airflow UI is automatically logged in as an admin with all permissions.
+
+To enable this feature, you need to set the constant ``SIMPLE_AUTH_MANAGER_ALL_ADMINS`` to ``True`` in the `webserver config file <https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#config-file>`__.
+Example:
+
+.. code-block:: python
+
+  SIMPLE_AUTH_MANAGER_ALL_ADMINS = True
