basic authentication

Hi all,

I am trying to think of ways that users of all ages can register and authenticate on a site without the traditional username/password. Examples like clicking on a series of images, dragging colored blocks into a sequence, or other 'brain friendly' methods would be great.

What are your thoughts on and experiences with 'passwordless' authentication? What are some solutions that have become popular? What are some innovative ideas that need testing?

Cheers!

Hi all!
I have now search the internet for about day to try to solve my questions.

I have Drupal 7, Service 3, Services Basic Authentication and have developed my own custom XMLRPC module (hook_xmlrpc). In this module I want to first see that the current users is authenticated. Then I want to retrieve some specific information from the user to be combined in with other information.

I know that the rest of this is working for user.retrieve over xmlrpc with basic authentication works like a charm.
