DocuSign authenticates via Microsoft Azure Single Sign On (SSO), and to increase security also requires multifactor authentication (MFA).
The login experience is 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. Next MFA prompts for Microsoft verification using the methods you already have in place.
To setup or change MFA verification methods, please see Actions.
