Saving Authentication Key

[ocbaker]

Without modifying your existing code the Application using your library is unable to save the User Authentication Key to use later. Which means when reopened a user with steam guard would have to login with their Username & Password and get another Steam Guard Authentication Code.

You need to provide a method/property for accessing the Authentication Key. So an Application only needs to ask for the Users Username/Password once if needed, and does not need to store them.
