We'll create fresh WordPress site with BlaatLogin: OAuth installed. You have 20 minutes to test the plugin after that site we'll be deleted.
The OAuth plugin for WordPress allows you to provide authentication against any
OAuth provider. This plugin is uses the OAuth library by Manuel Lemos. The
plugin allows the admin to select any from the services supported
out-of-the-box by the said library. Additionally it is possible to configure a
service manually, which means any site supporting the OAuth protocol can
be used.
