Best authentication system for production

Hello, i was watching many tutorials on how to build stuff with codeigniter but none of them actually tells you how to be ready for a production website. My main problem is the authentication pard. How do you register and login a user securely and be safe from sql injections and other harmfull stuf? I know that CI comes with security features but i dont know if they're enough to protect my site especially in authentication.
What is your opinion on the subject? What should i do to be ready for production?

I have the same feeling, any one have good authentication class?

Have you tried Ben Edmunds Ion Auth?

What about Tank-auth ? https://github.com/TankAuth/Tank-Auth
But it is not longer maintenance

I second @Dracula - Ion Auth is relatively easy to implement/extend and works well.

I use DX-Auth.

DX Auth has recently been updated to work with CI3.  I have used it on several projects and like it.

iWAT LLC - Application Development & Website Creation

i authentication library of choice is Ion-Auth. Been using it for a while now. And as was mentioned it is easy to implement, extend, and use, and it is compatible with CI3 RC2.

+1 for Ion-Auth

What about Community-Auth (http://community-auth.com/) ?
What's the general feeling about this library here ?

I am just about to start a new project and I was thinking about using that one.
