Authentication

I am not with or against having a standard CI authentication library but not having one is not a disaster and not even an issue. I think that many frameworks have so much libraries that make it more and more complex to deal with.

What I like about codeigniter is the simplicity, you have every thing you need to build your own application using the best practices. in the last years so many developers likes to depend on solutions that suppose to minimize development time or lets say they think it will make their life easy. Unfortunately I think this is not true, there is no such solution that can fit to all needs and trying making one will for sure make it more and more complex, and that's what many frameworks becomes.  

So search for library that fits your needs and If you didn't find, try making your own, this might be harder in the beginning but later, when start bug fixing, you will understand what I mean. 

Anyway I am planning to start an authentication library for (CI4), that fits my needs, and I will make it public hoping that someone can make use of it.
