`Twitter <https://twitter.com>`__ is a famous microblogging server.
Twitter use `OAuth <http://en.wikipedia.org/wiki/OAuth>`__ protocol to
allow applications to reuse its own authentication process (it means, if
your are connected to Twitter, other applications can trust Twitter and
let you in).

You need `Net::Twitter <http://search.cpan.org/~mmims/Net-Twitter/>`__
package, with a very recent version (>3).

You need to register a new application on Twitter to get API key and API
secret. See `Twitter FAQ <http://dev.twitter.com/pages/api_faq>`__ on
how to do that:.

Configuration

In Manager, go in ``General Parameters`` > ``Authentication modules``
and choose Twitter for authentication module.


.. tip::

    You can then choose any other module for users and
    password.


.. attention::

    inconsistent (e.g. Firefox doesn't block the redirects whereas Chrome
    does). Administrators may have to modify formAction value with wildcard
