GET Goatbucks, used to add funds (aka Goatbucks) to WPI ID, now authenticates via Microsoft Azure Single Sign On (SSO). This replaces the Central Authentication Services (CAS).
The login experience is now similar to accessing Office 365. Login with your WPI email address and password. The URL indicates a Microsoft address, beginning with "https://login.microsoftonline.com" and there is a background image of WPI's Earl Bridge.
