[quote author="Citizen" date="1311127285"]I'm sure this has been asked but the search feature on the boards isn't great. Can this be used on Codeigniter 2? Also, is this the most up to date one to use?

As in, there's no Ion_Auth v2?[/quote]

Yes, you can use IONAuth in CI v2.x
And latest version is posted here: http://github.com/benedmunds/CodeIgniter-Ion-Auth

Although there are not newer versions posted recently (AFAIK)
