Website Authentication module (1450813)

Hi, I want a login & registration functionality like <[login to view URL]> (open id based). In this, I would also like to add login via twitter. The code you give should be easy to integrate in any website. So you should give me a one-liner code, that I can use to display the login windows/buttons on any part of my website (for example while commenting). The websites that I will be using this are written in PHP, if that matters. regards, JP ## Deliverables **1) Neat, clean, maintenable code ** ** ** **2) The authenticated user's ID, and service provider information (whether it is google/facebook/twitter etc), timestamp, ip address, etc. should be stored in a MYSQL database table.** **After authentication, you should store the login information in the session.** ** ** ** **
