Plug and play login system?

Question

Does anybody know of a plug-and-play login system that supports existing logins like Google and OpenID? I am looking to implement something similar to that of Stack Overflows. Thanks!

RPX is indeed what I was looking for. Are there any other systems like RPX that do a similar thing?

Answer 1

RPX is likely what you're looking for.

EDIT: For similar solutions, Google is your friend. ;)

Answer 2

Authlogic is a plug-and-play authentication system for Ruby on Rails. Via it's plugin system, it supports Facebook Connect, OpenID, OAuth, and LDAP (among others).

Answer 3

I'm not sure about plug-and-play, but I started working with openidenabled.com's PHP library and it looks like it does the job pretty well with very minimal setup involved on the PHP application side.

Answer 4

You can also have a look at Gigya along with RPX.
