It is compatible with CI2.

Ion Auth v2 is available but it is still alpha, it is located here if you want to try it out: https://github.com/benedmunds/CodeIgnite...uth/tree/2[/quote]
Is v2 usable? I'm starting a new project and I'd like to use v2 if it means updating in the future is just an upload/overwrite instead of having to change all my code.
