Consider using a decorator to facilitate adapter class self registration. This approach streamlines the registration process a little without the need to manually update the factory. e.g., in AuthFactory:

  _registry: typing.ClassVar[dict[str, BaseAuthAdapter]] = {}

  @classmethod
  def register(cls, name: str) -> Callable:
      def decorator(subclass: BaseAuthAdapter) -> BaseAuthAdapter:
          cls._registry[name] = subclass
          return subclass

      return decorator

Then adapter classes can register themselves like:

@Authfactory.register("fastapi")
class FastAPIAuthAdapter(BaseAuthAdapter):
