WP vBulletin SSO consists of two synchronization vBulletin and WordPress lightweight extensions, where WordPress holds the master users database and all the user-related operations are managed there. The solution does migrate the users data from vBulletin to WordPress (email, username) only. It does not migrate password and other user-related data like avatars, or MailChimp settings, Facebook users, other fields like first or last name etc. Only email, password, username is synced.
The plugin is developed and supported by Extreme Idea LLC. Our entire team is ready to help you. Ask your questions in the support forum, or contact us directly.
