Secure Login

****Google**** Search engines are your friend here. ***Not Google, they are evil!*****

Even Bings first 3 results for "codeigniter auth library" are: CommunityAuth, flexiAuth, and TankAuth. My self, I like to use this one: https://github.com/benedmunds/CodeIgniter-Ion-Auth but would recommend communityAuth too as both of these are modern, up to date with CI3, well used and tested, well written and do slightly different things.

These days I often use my own library, but I am sure it is nowhere near as secure as those above, but in my circumstance security was less important than behaving in a certain way. However, I would not suggest this route, but rather that you test and play with the above and choose the one that you like, fits your needs and is the best solution for you.

Good luck,

Paul.

EDIT **** Realised my own cultural bias here, I hate google, cannot believe I wrote suggested you google. ******
