Great series, Alex! The only thing I was hoping to hear more on is the sanitizing of user input and best practices doing that with CI4.

I must to thank you so much Alex. CI4 manual is fantastic, but when i found your tutorials, oh, man, everything changed for me. NOTE: for the code to work (in my case), using CI version 404, i need to include this on filter functions after and before: $arguments = null. Otherwise, a fatal error. Thanks again :)

[MarioDanielCarugno]

Great work !
I just would ask for a 6th video showing how to integrate this Login system, from the repo, into an already existing project.
Not having a lot of experience on PHP and CodeIgniter, I don't find that task trivial or evident.
Thank you Alex !!
