What's the best practice for User Authentication?

[eluser]Unknown[/eluser]
I've done some searching and found a few different libraries and tutorials on how to do User Authentication for CI.

My question is, is there a User Authentication library out there that most CI developers use? Or do most people develop their own?

I'm just trying to determine what the common consensus is. If there is one.

Thank you!

Most end up developing their own but there are some very good ones in the Ingnited Code.

Personnaly I use Auth 1.0.6
It's small and fast.
