• The auth component uses the Auth class from lib/auth.py.
• This class defines abstract methods such as authenticate, is_authenticated and check_password.
• The BasicAuth class inherits from Auth and defines a basic authentication scheme using the user and password stored in the auth_basic setting.
• The NoAuth class inherits from Auth and disables authentication.
• The settings component uses the settings object from anthias_app/views.py to store authentication backend configuration.
• The settings_page view uses the auth_backends variable to display available authentication backends in the settings.html template.
• The settings_page view handles updating the settings with POST request data.
• The authenticate_if_needed method in Auth checks if the user is authenticated and initiates authentication if needed.
• The BasicAuth class checks the Authorization header for a Basic authentication scheme and compares the username and password with the stored settings.
• The BasicAuth class uses the hashlib.sha256 function to hash passwords.
• The NoAuth class returns True for is_authenticated and does not require authentication.
• The settings.html template displays the available authentication backends and the setting form.
