### Class

# Soup Auth

#### Description [src]

    abstract class Soup.Auth : GObject.Object {
      parent_instance: GObject
    }

The abstract base class for handling authentication.

Specific HTTP Authentication mechanisms are implemented by its subclasses, but applications never need to be aware of the specific subclasses being used.

`SoupAuth` objects store the authentication data associated with a given bit of web space. They are created automatically by `SoupSession`.
