After you've created your new app, copy the App Key and Secret Key (click the "Generate new key" button) from the App Details page and keep these for future steps.
While still on the App Details page, check the checkbox next to "OAuth" and enter the domain you've installed this plugin on.
Download, install and activate the LaunchKey WordPress plugin from the WordPress plugin repository.
Navigate to the LaunchKey settings section (WP Admin > Settings > LaunchKey) and enter the App Key and Secret Key you saved from step 3.
Finally, navigate to your Profile Options page by clicking on your username in the top right corner of the WP admin page and click the "Pair" link under the "LaunchKey Options" section. Next, enter your LaunchKey username and authorize the request on your paired device. When you're redirected back to the WP Profile Options page, you're done!
You will now be able to log in and out of WordPress using LaunchKey.
