[eluser]dungdn[/eluser]
I found many Auth Library source code at CodeIgniter/wiki, but i don't know which library is the best for a CMS or Ecommerce site.
Can anybody help me or someone make a review about them

Thanks

The best is whatever one does what you want it to do and the easiest for you to work with.

That being said, I like tank_auth, personally.

I've tried many over the years and ended up sticking with Michael Wales' Erkanaauth as it was the easiest to get running.
