Login Alternatives
------------------

The appearance of the Login dialog on a device depends on the following
settings:

-  The globally activated Login Methods. See 
   :ref:`User Authentication <ch-webapp-admin-options-user-auth>`.

-  The Terminal settings for the device. 
   See :ref:`Custom User Login <ch-webapp-admin-devices-terminal-custom-user-login>`.

-  The ``login`` URL parameter with the preferred login method.
   See |RST_LINK_APPENDIX_URL_CHEAT_SHEET|. 

-  Active :ref:`OAuth Client Plug-ins <app-plugin-oauth-client>`.

Terminal settings overrule global settings, and the URL parameter
overrules the defined default. When available, alternative login methods
can be selected by tapping the method button at the bottom of the
dialog. Some sample Login dialogs are shown below.

.. tip::

   A special URL path is available to use OAuth as SSO for User Web App.
   This URL can be presented on the site of an OAuth provider, to
   seamlessly link to |PRODUCT_NAME|. See |RST_LINK_APPENDIX_URL_CHEAT_SHEET|.
