I don’t know what your needs are or what you mean by “security extension”, but the pyramid authentication policy is very flexible. You should understand that it does not support users and passwords, it just provides a mechanism for obtaining a user ID from an incoming request. For example, AuthTktAuthenticationPolicy keeps track of the cookie user ID that you set using the remember method.
What significant information you receive from this user ID is entirely up to you and is application specific.
So there really is a question that you can ask if your application can "increase security".
