Question

Answer 1

Visit GitHub and search for Codeigniter Auth or Authentication, or check the CodeIgniter Wiki, you'll find many libraries with different features.. explore them and choose the one you need! But be careful, many are for CI 2, and you have to ucfirst the classes to use with CI 3, otherwise they don't work at all.
