Why do I want to use my WUSTL KEY?
Having a WUSTL KEY reduces the number of IDs you have to maintain. As the WUSTL CONNECT system grows, eventually it will be the primary University Login ID and password that you will need to remember. Limiting the number of IDs you have reduces the need to disclose personal information and the risk of identity theft.
Also, once you have logged in to a University system using your WUSTL KEY, you will be able to navigate to many other University systems without having to log in again during the same session.
