Multi authorization with CodeIgniter

Question

I have my own CodeIgniter webapp.

I want to add to my site the multi-authorization from Facebook, Google, Twitter and OpenID sites. (like here - https://stackoverflow.com/users/login)

Is it possible with CodeIgniter?

P.S. I've found some extensions for CI, but they are single and there is no way to merge them.

Answer 1

What is used in Stackoverflow is called OpenID. Knowing the name, you can search for OpenID+CI implementations and you'll find a couple of libraries out there, and I guess this is the latest one.

Answer 2

Facebook uses oAuth2 Twitter uses oAuth StackOverflow uses OpenID.

Merging 3 entirely different protocols is not easy work, which is why no easy solution exists. You'll have to get your hands dirty for this sadly.

The closest you'll get is:

That is not tested and I'm not sure if Elliot ever got around to finishing it.
