*Naming issue help*

I have a shared library across multiple apps. Lets say it provides `Authenticator` class which has `login()` function

Now, app B needs logout as well, so it extends Authenticator and adds `logout()` functionality.

How would you call such type? 

1) If I were to take inspiration from the way List interface looks I'd call it `LogoutableAuthenticator`

But such name looks silly for app B developers, as they only use a `Authenticator` which has both login and logout functions

1.5) Give it app name prefix like `AppBAuthenticator`. Also feels silly. All app B types then should have this prefix

2) Or, design it backwards, leave leaf implementations prefixless, so app B has Authenticator but it extends `BaseAuthenticator`. But this again looks stupid in shared code

3) Name them both Authenticator and let just the package name be different

Maybe just provide a single Authenticator class that provides a default noop logout implementation

Youd still have the same issue as app B needs the feature so it needs to name the type

I could how to makes sense to stick lpgout into the shared library and just not use it in other apps, buts that not the poimt of my question

You could use an extension method in B, so that you don't need a new type but in B the class simply has another method.

<@U0152P3VB5J> nice idea, flow is kind of like that right? but ill need to use the private / protected vals so no go
