=head1 AUTHENTICATION

As Twitter has now disabled Basic Authentication to access their API, to be
consistent Maisha now requires that access to both Twitter and Identica uses
OAuth.

With this new method of authentication, the application will provide a URL,
which the user needs to cut-n-paste into a browser to logging in to the
service, using your regular username/password, then 'Allow' Maisha to access
your account. This will then allow Maisha to post to your account. You will
then be given a PIN, which should then be entered at the prompt on the Maisha
command line.

Once you have completed authentication, the application will then store your
access tokens permanently under your profile on your computer. Then when you
next use the application it will retrieve these access tokens automatically and
you will no longer need to register the application.

For further information please see the Identica FAQ -
