few libraries

I addressed a very similar question in another thread a day or two ago ... there are too many divergent & conflicting ideas on what a minimal/appropriate "auth" package should have. The community cannot agree, so we have left the choice up to developers.

There are some several "auth" packages mentioned on the forum, including "Community Auth". That could be a good starting point.

thanks for your answer but in this way, I think there must be no helper and class in core library because each developer has a different idea
everybody that wants to choose a framework, searches for framework comparison tables and he sees that for example CI doesn't have auth library or REST library etc.
so he doesn't choose CI
I suggest that put a survey between developers and put useful classes in the core library
during the time, by getting feedbacks from developers, you can improve it to fit the developers needs
thanks again
