I have a custom web game I am developing and I'd like to offload the user authentication bits to a widget or some software I can leverage. As can be seen from: Best practices for web login / authentication? There are thoughts on what a good authentication system requires, not the least of which are lost passwords, captchas, email - none of which I want to redesign from the ground up.
So what software should I be using? I realize I could put a Wordpress/Joomla!/Drupal front-end on the site which would give me other benefits like user forums - but would that play nicely with "handing off" the user to my game system?
Of course my game has a database where user accounts are tied to unique character names - think RPG.
Thanks for any tips.
