One login for many codeigniter webapps?

Hi,

I have at least 6, 7 codeigniter 3.x web apps to handle my company operations. I would like to incorporate it as an ERP, so that user can have only one login and use required apps based on the permissions given.

Right now i have different login windows and sessions for different apps.

Any suggestions to do this?
is it possible to retain the session in multiple codeigniter apps?

You should look at simplesaml php OR read about SAML .  This is all about SSO (simple single login) then your problem should be solved!
