Best Auth library?

Seriously don't waste your time looking. This is an application framework, build your own. That's not always the case though. The Rails world has some pretty decent options. Django has a generator which will create the basics. I believe some of the other PHP frameworks have genators also. For CodeIgniter, you probably have to build your own.

That's not to say that any of the above mentioned systems will create exactly what you need. They simply give you a starting point.

Unfortunately, building a full user management system from scratch is a bit of work. On the bright side, once you have build one which serves your needs, you can probably use it for future projects.

The only one I have used is Redux, and I ended up tossing it.

One other thing to keep in mind. CI 1.7 has had big changes in form validation and session handling. I think for that reason alone all the old membership handling systems are obsolete.
